Having had a look at the travel books they seem to suggest a two week holiday doing a day of Disney / day of universal / water park / animal kingdom etc etc and staying centrally to everything.
However when I have been to Disneyland Paris I have found it far better to book into a Disney hotel and take advantage of the extra magic hours and fast passes.... (and we do go in early, we find it a real bonus!)
Universal seems to do this to but again for hotel guests - early entry into the Harry Potter part....
Would we be better moving hotel halfway through the holiday and doing one park then the other or is there another way to do this??
We are going in 2018 so plenty of planning time!!!
