We decided not to take our Bugaboo Frog. It would have been an absolute pain on the bus and would have taken up quite a bit of space in our hotel room. As much as I adore our Bugaboo (we've put tons of miles on it over the past 4 years) it just isn't great for travel. There was no way I was going to deal with the two part fold on the airplane or the buses.
We decided on two umbrella strollers. Our Maclaren Quest was a dream at Disney. The parks have very smooth roads/walkways, so it isn't like you need the big air tires of your Bugaboo.
I only saw one Bugaboo in the parks while we were there, but it was the Bugaboo Bee which folds all in one piece.
