We have a Graco Room for 2 (sit & stand type) My kids are 7 (size of 4 year old), 5, & 2 year old. I was thinking of taking this but then I saw the Apple Stroller deal for a City Mini Double and I am wondering if those strollers would be better for the vacation. Thoughts....my 5 year is a very, very slow walker and goes into tantrums when he gets overtired.
