I am going to Disney at the end of March, just me and my 6 and 4 year old. I have been before with all 3 kids and hubby, and just the middle kiddo but I can't quite figure out the logistics of rides with just me and 2 kids. Both are over 40" and love Goofy's Barnstormer & the 7 Dwarf Mine Ride. How can I make this work? Can the 6 year old ride by himself in a car while I ride with the 4 year old? Suggestions? Any other rides that I haven't thought of that might give us problems?
