Well, I just got it down even lower by prepaying, I figure it's not gonna get much lower than the $121 I'm paying now, and if it does it's only $5 to cancel. So now I've got an Equinox for about $15/day, all fees included!
DisneyPhD- Thanks for the info about the luggage fitting, I was orried since we'll basically be in the same situation... Let us know if you decide to go for sure, we'll be there at the same time.
The codes I used are from mousesavers, it was the newest rate code (it's in red) and the $15 off coupon link. If you're leaving before 3/31 there is a $20 off coupon link too.
