Rental and Party FAQ

​​

BOOKING PROCESS

​​

How do I check availability?

Available dates can change at any time, so it’s best to check the website booking tool to confirm your preferred date is open. If you need to ask questions first, you can submit a party request through our website and we’ll get back to you quickly.

​

What is the cancellation policy?

Cancellations made 21 days or more before the event date are eligible for a full refund or reschedule. Cancellations made 8–20 days before the event are eligible for a 50% refund, or a one-time transfer to a new available date within 6 months (no fee). Cancellations made 7 days or less before the event are non-refundable, but may be rescheduled, subject to availability, and will incur a $50 rescheduling fee.

​​

Do you give discounts for long or reoccurring rentals?

Absolutely, please contact us to discuss your needs.

​

Can I visit the space before booking?

Yes! Reach out and we can find a time for you to stop by.

​

BOOKING OPTIONS

​

What is the difference between a hosted party and a space rental only?​

-During a hosted party, a Mosaic Room staff member is present the entire time and can help with whatever you need. We will assist in setup, facilitating activities, cleaning spills, you name it. We can also provide tablecloths and party decorations if you like. 

-For a space rental, staff will meet you there to unlock the space and show you around, but will not be present during your event. This rental type does not include any tablecloths or decorations. You will need to pack out everything brought in, including decorations, food, personal items, and trash. 

​​

Can we enter early to decorate?

​Your reservation time includes total time you will have access to the space. Early access is not permitted and the space must be fully vacated by the end of your reserved time. Extra time may be added (purchased) if available. ​​​

​

Do you do parties for adults too or only kids?

We do both! And we can add on activities for adult parties also. We could do a dance lesson birthday (salsa, bachata, kpop, shuffle), we could do a paint party, or games. There are tons of fun options for adult parties.

​​​

​

ACTIVITIES

 

​​​Do parties automatically include an activity?

No. Activities are optional add-ons. Some families prefer to handle their own entertainment or have none at all, which is totally fine.

​

Can I add more than one activity?

Yes, you can book multiple activities. We recommend planning your timing carefully so guests have enough time to enjoy each one. 

​

How long do activities take?

This can vary quite a bit depending on the activity type and the age group. For example an art party for adults can last over an hour vs an art party for 7 year old kids we would try to keep to about 30 minutes max.​​

​

How does face painting work?

The face painting rate is per hour. Typically it takes an average of 5-7 minutes per person. It can be more or less depending on what designs are being requested. Face painter may be able to extend her time if available but not guaranteed.

​​​

Is pricing based on number of participants?

For add on activities that use supplies, activity pricing is based only on the number of participants. Most of these activities include 12 people in the price. Extra participants are just fine, but there is a charge per person to cover the added supply cost. Please let us know the week of the party what your final headcount is. We do not need to know your headcount for non-supply related activities.

​

Are activities done at the beginning, middle, or end of parties?

Totally up to you! Feel free to let us know during setup if you have an ideal timeline. We can go with the flow or make recommendations. â€‹

​

​

CAPACITY & SETUP

​

Do I need to decide on table setup in advance?

No. Just let us know what you’re thinking on the day of the party and we’ll arrange things to fit your group.

​​

How many people can the space hold?

The room can hold up to about 80 people without tables and chairs set up, though it starts to feel very crowded at that number. If we have a lot of tables and chairs set up, the max is closer to 50. Most of our parties are around 30–40 guests, which works very comfortably.

​

What tables and chairs are available?

We have 5 large eight-foot tables plus additional standard folding tables if more are needed. Setup is flexible and depends on your final headcount. We have 31 chairs. You're welcome to bring in your own as well.​

 

Can I decorate the space?

Yes! You’re welcome to bring your own decorations. Tape is fine — painters tape or regular scotch tape both work well. Tacks and push pins are not allowed, as they damage the walls.

​​

​

FOOD & DRINKS

 

Can I bring in food?

Yes, you’re welcome to bring whatever food you’d like. We have a partnership for catering with our neighbors Zylberschtein's and you can get 10% off if you'd like to use them. 

​

Can I serve alcohol?

Yes, but you must bring a valid banquet permit to the venue and follow all related laws.

 

​

MUSIC

 

How can we play music?

We have a bluetooth speaker for you to use the day of that you can connect to. For a hosted party, we are happy to handle the music if you prefer. The speaker is plenty loud! But if you'd like to bring your own, that's completely fine also. 

 

Can I have a DJ?

Absolutely — DJs are welcome! Live bands are welcome. Mariachi is welcome. Whatever you like!
