I know you can visit some theme parks at certain times of year to avoid many children, however what I mean are theme parks built more for imaginative and fun-loving adults.
Take some of the park rides you might find in family theme parks that appeal to both adults and children, but instead of avoiding elements that may confuse/frighten children, they’re allowed to get more detailed or whatever may be more fun for people. Fwiw I’m aware of some smaller scale themed venues (particularly some horror-related ones), but I feel like I’m blanking on any obvious larger scale ones.
You might enjoy cruise ships. They get a lot of hate but they’re an amazing vacation.
Endless adult-friendly activities at the destinations. All you can eat gourmet included in the price of the ticket. World class service from staff that actually cares. You even get to know the housekeeper on a name-to-name basis. Not to mention waking up to a different view out your balcony every morning. It’s worth it for that alone.
Meh. Cruises are boring as fuck. I guess they are OK if all you enjoy is getting wasted
