This problem may be related to you. Do you play more than one HTML game and which browser do you use?
As a solution, i found these:
-Make sure your device's disk space and memory aren't full or close to their limits (this should be an uncommon issue, but still a potential problem).
-Load your latest save (if you've come accross the localStorage quota error, it's possible that some variables have got corrupted).
-Save the game as a savefile using the "Save to Disk..." option in the Saves Menu.
-Turn off [any kind of] auto-save feature (It's not something you can do).
-Delete your saves stored in memory in the Saves Menu.
-Clear your browser's cache and cookies (by far the most helpful).
Using another browser may solve this problem.

I'm on day 30 in my save and it only uses 0.02% of the browser's local storage. In the next update we will add a button to turn off auto-save. I assume you only have this problem in the hotel room, because the game only does auto-save there. There are a lot of browser plugins called "Local Storage Manager". You can also look at them and see what is causing problems.
