We’ve been in September (in school time), twice in May and once in August.
Personally would never go in a colder month. It will still be busy enough.
Plus, if you do get annual passes, one of them includes magic hours (early access to rides).
Plus, they do fastracks, for free.
We’ve done all UK theme parks, and DLP. Absolutely love DLP.
We did first holiday in May for around £1200 for the week for 4 of us (hotel apartment £600, Eurostar £200, annual passes £400 ish)
Went back in August for one week for £700, as already had passes.
They went back following May, for £900, for a week.
They were bargains though, I researched like a demon.
But we had a whole week there, watched fireworks every night, went into Paris too, saw Eiffel Tower etc.
As we’ve done whole weeks, we never get anyone trying to pack it all in on a weekend. It’s impossible.
We have done Disney hotels too (dream, explorers) but our favourite place is the hipark. It’s lovely. One room in a hotel vs an apartment and cooking facilities. No contest.
Food on site is awful, but there is a Mac Donald’s in the Disney Village area.
We cannot afford to go back, it was a one off (3 times in one year!) but it was the best time of our lives bar none, and would love to help others get a good deal.
