OK so for the room, if you do the dream weekend Friday/ Saturday quad, 4 to a room.
It's $336 - the $75 deposit / by 10 months = $26.10 per month to have it paid by the deadline of June 22, 2009 = 87 cents per day
For the Early Bird which is Thurs/Fri/Sat scrapping Fri/Sat quad:
$375 - $75 deposit / by 10 months = $30 per month, that's $1 per day.
Or you can do what we did and book a 2 day local package for $202 and talk directly to the hotel to be a 5th person in the room. that is 202 - 75 / 10 = 12.17 per month or 43 cents per day. I believe the room was something like $15 per day for the 5th person.
then the flights, just keep looking for deals through Southwest.
And the key thing is you need everyone in your room on the same package.
