In deciding whether to take your own or not, you may want to consider that rentals have to be turned in at the front gate, so you can't stroller a sleepy kid back to the room, also the rental's don't fold, so you can't take them on the monorial or the railroad. We rented last week and it was fine, (since my dd is almost 5 and we don't own a stroller anymore) but people who had their own had some advantages. Note, if you rent, take an inexpensive scarf and tie it on the handle so you can find your stroller in a sea of rental strollers, this worked great for us.
