We are always in the same predicament as you. There are other options for play spaces than inflatables, but the cost for most party packages is for up to 25-30 kids, so it's pretty expensive to have a party for a dozen or so kids yet home isn't an option. We went to Adams Park (I think that's the name) in Lincoln Park just south of Armitage just before Labor Day last summer, the last day the water play area was open. There's a nice playground with a sandbox full of toys. It will be too early for water play, but they have a rec room that you can look into renting for the party. You'll have to bring everything in yourself, but the kids can play outside then warm up inside with food/cake. If it's really cold or rainy, you'll have to plan for an indoor activity because it really is just an open room. I've never had a party at the park district, but I think it's pretty inexpensive. I believe a downside is that you don't get a "helper" for setting and cleaning up, so it ends up being a lot of work for you during the party. If she loves music, you can look into a place like Gymboree where they have people leading activities, but Gymboree parties are expensive if you're not a member. We have 2 kids and have had parties at Kid City, Fantasy Kingdom and My Corner Playroom. This year, we're looking at Pump It Up or Little Beans Cafe for my son's 4th. Good luck!
