Yea, we found we get he same gas mileage with or without the boat behind us! Guess it does help having that gas guzzler!
We've logged over 200 dives in our own boat around the keys, mostly around Marathon, so we have done this a few times before. Most of the time, we sleep on the boat, so no problem with accomidations. This time a couple of wives want to go, but they don't seem to like the idea of sleeping on the boat, so hence the campground question. Also, we'll probably stay a little over a week and that a little too long for small boat quarters.
Cheap?
Hmm 1 week trip.
A 2 tank dive trip a day for 6 days, @ $300 X 4 divers = @ $1200
-OR-
Extra fuel, @ $300, Couple of fill cards, @ $100 = @$400 + a little extra work hauling the boat, ect.
You wanna hear cheap? I've done this trip with 2 loaves of bread, peanut butter and Jelly, and some sliced turkey!!!
Hmm, I think my wife is right, I AM a cheapskate!

PS yea, we left our boat for the first year or so before we wised up and started making sure to invite a non-diver to stay with the boat!
