Is there a deposit fee?

I didn't pay one. I booked through booking.com and paid the full amount when I checked in.

Yes

When you book directly at 800-641-0011 we require 50% of your stay as a deposit in order to hold your reservation. You can pay remaining balance at the chack-in

I stay one night, and didn't have to pay a deposit.

Yeah.
