Hi!
We like to use the room key for everything except those $5-$10 items you may need throughout the day. Just be aware, the spending limit is $500 unless you go down to the front desk and ask for more after the initial $500. (I have heard that the limit gets higher with the hotel category, but we have only charged to the room the past few trips to POP.) I had thought that the limit was $500/day, and that at the end of the day it was posted to your charge card and you got another $500, but this is not the case, as I found out the hard way....getting turned down in a store. Have fun!
