How long do you hold the 100 deposit after you rent the room

They return it in about 7 to 10 days if there's no charges to the room.

I haven't received the statement on the card I used. The only thing that matters is that you get your credit back. I wouldn't think it would take that long.

Until you checkout, then it is returned.

Not sure

Should be until payment is processed

3-5 days

I do not know. I've never stayed in the hotel

After you leave. It's there incase you take stuff, like pillows or blankets.
