What about simply reserving one of the picnic areas at a local park? In the past year, we've been to great b-day parties at Finch and Erwin Parks in McKinney, and Celebration Park in Allen. October 12 is probably a little late for the spalsh pad, but kids will still have a great time on the playground (the party at Erwin did bring more activities--chalk, bubbles, arts and crafts--because there wasn't a big playground). I say, keep it simple! GL!
