I had to ask on this one because I wasn't sure. Anyway my contact at the Marriott says:
The charge for wireless on the convention floor and in meeting rooms is the same for a hard wired connection. The discounted rate we have offered SND is $500 per day for the set up and $75 (one time charge) per additional user. Individuals can access wireless hot spots in other public locations throughout the hotel (lobby, food court, pool deck etc). The charge for this is $14.95 per day.
Wow. $15 clams a day ... the Disney resorts only charge $10!
This is when your will power REALLY gets challenged!
Having wi-fi access available, even at a cost, and NOT connecting, for me, is like putting me in a room filled with hot wings and asking me not to eat any of them.
