If you're looking for comparisons:

GOBA is five days, gear hauling (including your own tent), campsite fees with showers, and sag only, maximum of $200 before discounts for club membership and early registration. Because it's such a large tour, lots of non-profits along the route offer community dinners fairly inexpensively.

XOBA, a much smaller tour, is seven days, all of the above plus the option for sleeping in gym spaces, two dinners, one box lunch, T-shirt, and transportation from the end point back to the start. $300 before member discount.

Bike Florida is seven days, similar lodging options, $450 includes 6 breakfasts and 5 dinners.
