We also have twins, but girls so it may be a little different than boys. We did bring our double jogger to disney when they were 5, mostly for the same reasons as you are thinking -- they were wiped out by night and it was handy to let them have a seat. Another reason, though, is that my girls LOVED getting the jogger ready for night time fun -- they'd pack it with light-up toys, favorite stuffed animal, etc., and then really look forward to getting cozy together especially when it was time for fireworks. I'm not sure if boys would feel similar, but my girls just loved it. It actually added to our fun because if by chance the girls fell asleep in the jogger, DH and I would just take our time and stroll back to our resort, grab a snack, talk, enjoy the sights.
It did make a difference where we stayed, though, to be honest. If we stayed at an Epcot resort, we'd end our night in Epcot so that we could just walk between the park and our resort (no unloading and folding jogger). And if we stayed at a monorail resort, we'd end our night in MK usually (sometimes Epcot) so that we could just roll the jogger on and off the monorail.
We would've probably done things differently if we stayed at a bus-only resort as it wouldn't have been very convenient with our jogger and sleeping twins on a bus. Not sure what we'd do with a rental car. But I do think in your shoes I'd be sure to have a comfortable jogger on hand at least for nights. For what it's worth, my twins also never used a stroller here at home, local zoos, etc. But Disney World was a whole different situation for us and we never regretted having the jogger along.
