HEY!! Got your post about the strollers. I really am torn as to what to suggest you do. Here is the breakdown:
Positives:
*Easy to board transportation without having to fold a stroller.
*Very easy to push. My arms were NEVER tired.
*Easy brake system on the back.
*Cup holders and pockets.
*Can just leave them wherever you want and the CMs will take them to the front for you at the end of the day.
*And my BIGGEST positive (and the one I am conflicted with in your situation) is that it saved us LOTS of time having Abby ride. She tends to look around and does not pay attention when walking too well

We frequently trip over her when walking as a family. hehe Also, she is still young (and I know Ally is one year younger) so walking all of the parks for 5 days straight is really hard on their legs and feet. I am curious how Ally did with that on your last trip. With that being said, we feel that Abby can handle it when we go back in December and will have to walk. She will be 7. Honestly, I totally think she could have handled it this trip, but it would have made her tired easier. Make sense?

*You wont have to check your stroller on the plane.
*Seat belts.
*REALLY easy for the kids to jump out quickly to see a character, ride a ride, etc. Also, you dont have to "tell" your kids where to go. For example, when I saw a character spot, I would just wheel them over instead of having to get Abby's attention and then let her know who was there and where they were. I was in control, so it saved time.
Negatives:
* Too short for our older kids.
* Tight fit with both kids in the double.
* Expensive (verses bringing your own).
* BIGGEST FOR ME: No stroller to use to and from the park, on the boat docks, through the lobbys, up the elevators...you get the idea

We had to chase after Aiden on the boat docks and hold him while walking into the parks. Phew! It can be tiring.
* DOES NOT RECLINE! So, no naps in them at all! I thought maybe the seat would be wide enough to lay him down...nope.
* If you get on the train, there is no guarantee to get one on your next stop. You must leave them before boarding the train.
I am going to get a new Maclaren stroller for my birthday I think. I really need a new stroller and I have heard good things about the Triumph. We will bring it with us in December. I also like those strollers that let the older kids ride on the back...but I think Abby is too heavy. She is 53 pounds and the limit is 40 or something
Sorry this post is so long! Just want to help you make the right decision!
