Going in a couple of weeks....was thinking of renting a double stroller for twin 22mo olds but now am thinking of buying. Not sure...wanted to find out if it is worth it with the baby joggers. Here are my ?s and hope someone can help. (1) What is the difference between the regular baby jogger and the "mini"? (2) How long can you use them...I know they always give "weight" limits but really how long do they really last? The jogger? The mini? With my twins 22 mos...can I use until they are 3 or even 4? (3) Why the baby joggers ...what is so special about them? (4) Is the mini better able to fit on monorail etc. than the regular jogger or are they both easy to load on monoroail, tram, bus etc.? (5) Finally, is it worth buying for the trip? I already have a double jogger (too big and heavy for Disney). Is this brand worth buying to have for future Disney trips. I just don't want to rent this one and then wish I would've bought it. Sorry for all the ?s...I really appreciate any feedback.
