Summer is just around the corner (for some of us), and that means…it just might be time for a vacation. These five mind-blowing hotels range from the luxurious Ithaa (above) to a strange Alcatraz Prison-themed hotel in Germany. Continue reading to see them all.

5. Bubble Hotel

Created by French designer Stephane Dumas, these $700/night bubble pods let you experience the great outdoors without getting dirty, complete with a clear view of the night sky.

4. iPod Hotel

Yotel’s iPod Hotel — yes it’s actually named “iPod” — looks like something you’d see on the set of a sci-fi movie, complete with “space capsule bed nooks, rounded corners on nearly everything, and a computerized self-serve check-in system.” The good news is that if you have no plans to travel outside of the U.S., you can also experience the Yotel in New York City for about $379 per night.

3. Alcatraz Prison Hotel

No, this isn’t a theme park, but rather a real Germany-based hotel inspired by the famous Alcatraz Island prison. Located in the Kaiserslautern area, “guests who want to spend a night behind bars can expect to pay around 50 euros, or 70 dollars (USD), for the experience.”

1. Ithaa Underwater Hotel

Hilton’s Ithaa resort is unlike any other because it featured an underwater bedroom, which is currently a 12-seat restaurant. Plus, “the Maldives hotel boasts 50 luxurious water villas, 79 exotic beach villas and 21 fabulous spa water villas with private treatment rooms. On land, the stunning living areas are arranged around courtyards with a fountain, while huge outdoor garden-bathrooms offer a taste of the tropics, enormous glass doors substitute for walls and ingenious landscaping ensures total seclusion.
