We're planning a mini-vacation and I've never been to Indianapolis. We would be coming the 4th of July weekend my husband and I with 2 girls (11 and 7). I'm wondering if there are outdoor waterparks or pools? and which area is "safe"? There are so many hotel choices (downtown vs south vs airport etc). We would be driving so will have a car but love if we can walk around too. The canal area looks nice? Is there enough to keep us busy for 5 days? We're not really museum type people but like activities (swimming, go-karts, ) Any advice would be appreciated!
