Our family of 3 is going to Orlando for 2 weeks this summer, one week of Disney and one week of Universal. Since we're staying at Saratoga Springs for our Disney week, my wife wants to skip the rental car and depend on the WDW transportation for that week. That makes me nervous since I've never been without a personal vehicle on a trip like this. Also, we're traveling at near peak season (last week of July) and I'm worried about bus delays due to crowds. Any advice would be helpful. Should I be worried about this, or is the Disney transportation reliable enough? We're planning to be at each park at rope drop and probably stay until closing.
