Room charging?

[MickeyFlirt]

I want to charge to my room key as I did this last time we went, but I am not taking a credit card(also did this last time...Way to tempting...Went a little over budget ) I am taking a debit card which I know can be placed on charging. My question is when they put it on I know they they confirm the CC has money on it does anyone know how much money they confirm it with. Also can i place down cash or traveler's check to be used first than go to the debit card? did I make any since?

They confirm it with $1. I haven't had any problems using my debit card.
