What is the most economical way to rent a minivan or full size suv for a week long trip from Lexington KY to gulf shores al?
Start calling rental agencies at the airport and whoever offers the best deal, go with it.
Call around local car dealers as well. Most have loaners for people whose cars are in for repair which they might rent to you cheap.
Ask around friends and relatives, see if one has one they'll let you use cheap.
Best I can do.
Are you planning on returning it back to Lex or turning it in at Gulf Shores? One way rentals are always more expensive than round trip. Are you a Costco or Sam's Club member? I recently needed to rent a car and found that Costco had the best pricing. I was able to rent a full sized car for a week for less than $200. However, van and SUV rentals are always way more expensive than cars. Check with sites such as Expedia, Kayak, etc for pricing. For this busy travel season I'd say the posted prices are what you are going to have to pay (and it won't be cheap).
