Yesterday I couldn't log in, and my hotel had vanished. It's fixed today, but I was wondering what happened.

yes... same here...

if the site goes down, i think it has a back up data base that show what you saw, i too saw this, i think it happened twice in 3 days, these things happen on all games from time to time, with power surges and the like with server etc. so i imagine that it will happen again, but it will always be fixed, barr 1 time, when it never comes back again, lol
