Frequently Asked Questions
Are birthday parties at The Slimee private?
We offer both private and non-private party options. Private parties include exclusive use of our party room, while non-private options share the space with other guests.
👉 For details on packages and availability, please visit our Birthday Reservation Page or contact us directly—we’ll help you find the best fit for your celebration.
How early can I arrive for my party?
You may arrive up to 15 minutes before your scheduled party time to access your party room. We kindly ask that any birthday banners, goodie bags, or centerpieces be pre-assembled so they can be placed quickly and easily. This helps us keep everything on schedule and ensures your party starts right on time!
Are there extra fees if we go over the package limit?
If you’d like to add more children beyond your package’s maximum, the cost is $35 per additional child.
For parties that exceed the package limit, a 15% service fee will also be added to the final balance. This helps us provide extra staff and resources so every child enjoys the best possible experience.
What if I’m unsure of my final guest count when booking?
Start by booking the basic package. We’ll reach out by text 2–3 days before your event to confirm your final headcount. The number you provide will be the count we prepare the room for.
If your actual attendance is within 3 guests of that number, there’s no extra charge. If the difference is greater than 3, we will charge based on the final headcount you confirmed by text.
Do you provide party supplies?
Yes! We provide lab coats, lab glasses, utensils and cups for kids to make the experience extra special, and we handle all the set-up and clean-up so you don’t have to worry about a thing! You can bring your own decorations to the party too.
Is there a minimum age?
Our parties are perfect for all slime lovers – kids, adults, everyone welcome! We recommend it for children ages 3 and up. Younger guests are welcome to join in sensory slime play, and with our guidance, they can create age-appropriate slimes that are less sticky, easier to handle, and free of small charms (to avoid choking hazards).
Do you offer catering?
We don’t offer catering right now we serve Pizza for kids.
Can I bring ice cream or ice cream cake?
Unfortunately, at this time, there is no refrigeration available for these items, sorry.
Can we BYOB?
Family parties are welcomed to BYOB for their guests 21 and over, we can provide a sectioned area for drinks.
Do you offer party favors?
Each child’s personalized slimee in its container makes for a perfect take-home party favor! In addition you can buy our premade slimes as a party favor and add your bags.
Do parents need to stay?
Parents are welcome to stay and enjoy the fun. No need to buy ticket for parents.
How long is the party, and what happens during the event?
The party lasts for 1.5 hours, divided into three fun sections. The first 15 minutes are for getting settled—guests put on lab coats and glasses, and we wait for late arrivals. The next 45 minutes is a slime workshop led by a Slimee expert, where each child creates and customizes their own slime, adds a piece to our Slime Wall, and receives a Slime Expert Certificate. The final 30 minutes are for celebrating the birthday star with a birthday song, and a group photo. We don’t provide the cake, if you bring it we will serve it.
What is your cancellation and refund policy?
All reservations need $200 non refundable security deposit to book the date. A minimum of 1 week notice is required for any date/time changes or cancellations.
