its just the way we do our trips and it can be a bit fiddly but is ultimately worth it because when it works you have had a good nights sleep the night before and arent all tired from travelling when you arrive in the parks, right from the first time we arranged our own transport we have always travelled the day before, we usually only stay in 2 hotels one a disney hotel such as the sequoia and one offsite such as the explorers because as you know your first day in the parks is your arrival day, so we travel the day before and not loose that first day by travelling, as for the 3rd hotel this time around it was cheaper to book that 3rd hotel and travel home on the Tuesday than it was to travel home on the Monday and it worked better timing wise for our connecting trains when we got back into London.
