My 3 year old's birthday pary is Sunday, and it is supposed to be at a park in Brookline. Now Irene is going to be causing storms, so we need a plan B. I looked at our Y to book a party, but man, they wanted almost $300. Are there any semi-affordable playspaces in Brighton/Brookline? I can call to see if they have last-minute accommodations,orthewise, I guess the party will be postponed. Stupid Irene.
