We are taking our son and daughter to Disney in September. I plan to rent a ciity GT but cannot decide if I should get two single strollers or a double. Son is turning 3 a month before we go and daughter turns 6 while we are there. Neither use a stroller at home, but I know both will use it while we are there. My daughter likes to aggravate my son, so I originally thought it would be easier to get two single strollers (also easier to split up). Now I'm thinking the extra cost and hassle might not be worth it. It would be almost twice the cost and that would be 2 strollers to deal with throughout the day and on busses. On the other hand, a double might be hard to fold and deal with as well, especially with over 80lbs in it. What are your thoughts?
