Whichever reservation you don't pick up and take will not be charged. Just make sure at the gate they pull up the correct reservation.

Having an intermediate reservation would also give you the option to negotiate for a large SUV upgrade at the counter if there's not a big line. Just know your numbers and be willing to negotiate.

Also, finding a vehicle with built-in navigation these days is a little tough, but not impossible (just like the SUV in select & go).

and FWIW, you'll be hard pressed to find ANY rental company on Yelp that doesn't have negative reviews.

Hope this helps!
