You have to do self check-in according to an email you would get, but I haven't get any email until the day of check-in. You would have no phone number, any line to contact them. What I could do was waiting in front of the main gate until someone opened the door for me. I barely entered there, and the front person said my email might be wrong or hotels.com had a problem, never said their system is wrong. She said I would get an info for opening gate sometime soon so I believed her and left, but it didn't arrive again, so I had to wait in rain AGAIN until someone opened the door for me. I got in anyway, the capsule was dirty, there was no 110V inlet, and all the spaceship-themed panels, digital clock were just FAKE, printed paper lol. More annoying thing was I finally got that email for checking-in at 10 PM. Would never go back again.
