Moab can be as expensive or as cheep as you want to go.
Some costs that can't be avoided are some park fees. You may want to budget about $40 for the week.
Camping can be free or at a private campground at around $20 a night.
Food, kind of depends on what you want to eat. There is a market in town as well as a bunch of places to eat out.
Gas prices are going be in line with what you are paying for in Honolulu.

There are no fees for goneMoab, but we are going to be selling t-shirts (about $15 each, details to follow). We are also going to have a raffle at $10 a ticket.

If you drink then figure on paying a few extra bucks for booze.

After living in the land of island prices you should find Moab to be no big surprise.
