$9.99 is a steal compared to some hotels.
At the MGM Grand in Las Vegas we were charged $19.99/24 hour period for EACH COMPUTER in the room. I was there for conference and we had 3 computers going between myself and roommates.
Over the 6 days we were there, ~$360.00 in internet charges alone tacked onto our bill. Makes my $70.00 bill at Disney not so bad I guess.
