Where to next? Help us decide
Time to decide next big trip for summer 2018.
Option 1: Europe (thinking Futuroscope, Disneyland Paris, London, Efteling, Europa Park).
Option 2: Aulani and Tokyo Disneyland
Which one would you choose for summer 2018 and why?
Tokyo Disney Resort is amazing, as is Japan as a whole, and is well worth visiting at some point. However, I would strongly advise against visiting it in summer of 2018.
I would suggest if you're doing Europe, Don't forget Alton Towers and Blackpool.
While I've never been to Japan, I did a two week trip to Europe several years ago and it was excellent. On that trip, we spent the first couple days in London, then flew down to Venice and drove from there to Paris via Chamonix and Normandy. Unless you're going to London due to flight prices, I'd probably stick to mainland Europe if you aren't also planning to see more of the UK. While I liked the city, it is a bit removed from everywhere else on your trip, and you could use the time you'd spend sightseeing there elsewhere.
Go to Europe during the World Cup. Lots of local tourists will be on Russia or at home watching the games. Theme parks and other tourist attractions on Western Europe will be less crowded.
A couple of weeks in the UK, visiting the theme parks and other 'touristy' stuff, might be another option. As Chad mentioned, Alton Towers, Blackpool and Thorpe Park are well worth a visit. AT has SW8 opening in 2018 and that looks good so far. AT also has the best coaster in the UK (my opinion :) .. ) in The Smiler. Thirteen and Nemesis are also awesome rides. Blackpool is a typical English seaside town (with some great coasters) and is an experience beyond all description.
