Curtis Blues did a fabulous acoustic blues show for our kids' birthday parties around that age. He can play, tell stories, and get the kids playing too. The parents enjoyed it. I don't know if he still does birthday parties so you'd have to ask him. Here's his website. https://curtisblues.com

Do a trampoline place or a gymnastics place.

Reserve a room in a DPR rec center with a playground outside (so it's an option if weather is good), then DIY according to your kid's tastes.

- craft project that serves as party favor
- decorate cupcakes or cookies
- magician
- classic party games like musical chairs, hot potato, freeze dance

Dynamite, agility center

We’ve done Little Gym and MyGym around that age, is there one near you?

Looking for recommendations around NW DC or Bethesda for a 5th birthday party this summer for ~15 kids. Would prefer indoors because of the summer heat/chance of rain. Have done Silver Stars already but not opposed to something like that again. Thanks!
