About

Call or check the calendar before you drive, because open play here is not guaranteed. The venue says its open-play hours vary; one reviewer was turned away at the door on a Sunday afternoon because a party had the space, and another was told outright that children couldn't play on weekends. Parties shape the day in other ways too, and one party parent describes the narrow entrance hallway jamming at changeover, one group leaving as the next arrives.

When it is open, the draw is the Little City, a pretend-play village sized for children from birth to about eight, with a pizzeria that one reviewer's daughter picked as her favorite corner. Classes are a big part of the program, and several parents write more about the teachers than about open play itself.

Parking is tight, which two visitors mention, so leave a few minutes to find a spot. Card payments carry a surcharge over the posted cash price. A toy boutique sits alongside the play space, which is worth knowing before you walk a preschooler past it.

Birthday Parties

Plan this one for a toddler or preschooler: the birthdays reviewers name here are second and fourth birthdays, and one guest with children of two and four ranks it among the best on the island for ages one to seven. Three party leaders run it. The venue is full-service and allows no outside theme items or balloons, and it recommends booking four to five months ahead.
