Psst. If you get a room at the Doubletree Berkeley Marina hotel, you get access to their indoor pool, which, sources tell us, makes a great winter birthday party for kids who have outgrown jumpy houses.
A family can stay overnight in the room, or a really cool parent could offer to stay with the birthday kid and a couple friends for a small slumber party, and then make use of the pool during the day. Pizza delivery can be ordered to the room, but be warned that the rooms are small and kids will be sitting on the beds or floor to eat.
Both Sheraton Four Points and Hyatt House have party-worthy swimming pools and are walking distance from Bay Street and Public Market for proximity to movies or shopping.
