In my opinion, you should go to italy . you can fly to the island Sicily Italy and there take a hotel or something different you want to live in in catania. There you have the Etnaland which features some nice themed rides and also a Mack MegaCoaster called "The Storm".
If you want more thrilling adventures, you might also go to Venezia or right at the border of the lake garda and visit the Gardaland. There you have the first ever built Wing Coaster by B&M and some other nice thrilling rides as well as a SLC (kind of not that bad over there). If you plan to visit Gardaland from Venezia, it takes you like two hours to get there but it's also worth to stay at the lake garda for a night or so.
Hope that my advice was helpful in any way, have a nice trip
