Wonderfly Arena
Vendor Program
Wonderfly Arena hosts more than 900 private events a year in Arbutus and Timonium. Every catered meal and every bar at those events is provided by an outside vendor. We do not run our own food or beverage program, so nothing here competes with you for that work.
Founding Vendor enrollment closes November 7, 2026. $250 per year instead of $500.
Founding Vendor enrollment closes 11/7/26. $250/year instead of $500.
A vendor program built on real event volume.
900+ Events Per year
Birthday parties, corporate outings, mitzvahs, school groups, and large family celebrations, across two Maryland locations. Event sizes run from a dozen guests to several hundred.
All food & beverage is outsourced
Wonderfly Arena does not operate its own catering or bar service. Every catered meal, drop-off order, and bar service at our events comes from an outside vendor, so there is no internal program competing for the work.
Two Maryland Locations
Arbutus, off I-695 at 4811 Benson Avenue, and Timonium, at 1913 Greenspring Drive. Roughly 13,000 square feet, serving Baltimore City, Baltimore County, Howard County, and northern Maryland.
Clients ask us who to use
Most clients book the room before they think about food. Our sales team and general managers field that question every week. Preferred Vendors are the names we give.

How the program works
Two tiers, your choice
Any vendor providing food, beverage, or bar service at a Wonderfly Arena event works under one of these two agreements.
Preferred Vendor
Reduced per-event fees, marketing exposure & operational benefits.
Annual fee: $500. Vendors who have already worked events here qualify for the Founding rate of $250 for as long as they stay in good standing. See below.
Standard Vendor
Available to any approved caterer, bartender, or food service partner.
Vendor Fee Structure
Transparent per-event pricing
What the percentage applies to. Fees are calculated on the client invoice subtotal. That includes food and beverage sales, service and labor charges, and any vendor markup on rentals. It excludes sales tax, gratuity paid to your staff, payment processing fees, and documented pass-through costs billed at cost with no markup.
Service Category Category | Preferred | Standard |
Full-Service Catering | 9% | 14% |
Drop-Off Catering | 7.5% | 12.5% |
Bartending Services (client BYOB) | $45 flat | $95 flat |
Licensed Bar/Cash Bar | 9% | 14% |
When one vendor provides both catering and alcohol service at the same event, the Full-Service Catering rate applies to the combined invoice.
FOUNDING VENDOR INVITATION
Vendors who have already worked events at Wonderfly Arena can enroll as Founding Vendors at $250 per year instead of $500, locked at that rate for as long as they remain in good standing. This invitation closes November 7, 2026 and does not repeat.
What to know
Things to know about the space
- Equipment/amenities available for your use: Rolling bar, staging space, tables, chairs, water access, power access, trash & dumpster access.
- There is no commercial or warming kitchen. On-site cooking or heating equipment needs written approval in advance.
- No open flame indoors and no deep frying.
- Guests may not self-serve alcohol at any event. All alcohol must be served by a certified bartender.
- At BYOB events, the client purchases and owns the alcohol. Vendors cannot buy or supply it on a client's behalf without a SCAT license.
If the program does not produce work for you, the fee comes back
If a full membership year passes with zero bookings through the program, and you have stayed compliant with insurance and licensing requirements and responded to the client inquiries we send you, we will refund the annual fee in full. This is written into the agreement.
At the Preferred rate you keep 5% more of every invoice than a Standard Vendor. On a $1,000 event, that is $50.
The annual fee pays for itself in about ten events at that size, and faster on larger ones. Founding Vendors at $250 break even in half the time.
Requirements to work events here
- Commercial General Liability insurance
- Liquor Liability insurance for any vendor that serves, supplies, or handles alcohol.

Frequently Asked Questions
FAQs
With the client. You set your own pricing and menus and you invoice the client directly. Wonderfly is not a party to that contract. The Venue Access and Operations Fee is what you pay us.
No. The fee is your obligation to Wonderfly and cannot appear as a line item on a client invoice under any label. You are free to reflect it in your pricing.
Your client pays you directly on your terms. Preferred Vendors receive one consolidated Wonderfly invoice per month, itemized by event, on net-10 terms. Standard Vendors pay an estimated fee before load-in and reconcile after the event.
Six per location for full-service catering, six for drop-off, and three combined for bartending and licensed bar service. Slots are awarded on quality and fit, not on order of application.
Yes. We track approved vendors in other categories for insurance purposes at no charge. The paid tiers currently cover food and beverage only.
No. Preferred status is not exclusive and does not guarantee volume. What it does is place you on our vendor page, in tour folders and rental guides, and at the front of the list when our team is asked for a recommendation.
Preferred Vendors are expected to complete at least 10 paid events in a rolling twelve-month period. If a full year passes with no bookings through the program, the performance refund applies.
Preferred Vendors can, with approval for anything featuring our logo or the Preferred Vendor designation. Standard Vendors may state factually that they work at our facilities but cannot use our name or logo in marketing.
The Timonium event space is on the second floor and features a loading dock with ramp access as well as an ADA ramp for cart load-in from the ground floor. Arbutus is on the ground floor with dedicated parking. Both have designated load-in areas coordinated with the manager on duty.
A rolling bar setup at both locations, plus staging space, water access, power, trash, and dumpster access. Drop-off/delivery vendors should arrive with the food ready to serve since there is no kitchen for cooking, reheating, or refrigeration. Bring your own serving equipment, hot boxes, and utensils. Anything that cooks or heats on site needs written approval in advance.
