When I travel by myself I usually use priceline for my car. I'm unwilling to rent from a company that treats domestic partners differently than spouses when I travel with my partner. I'm fairly certain the 5 companies that priceline uses for bidding in Las Vegas treat partners the same but I wanted to see if others have had any bad experiences with any of these in LV at the airport:
Avis, National, Alamo, Budget, Hertz.

We've rented together from Avis and Hertz in Vegas but not the other ones. Sorry if a similar thread has been posted. I didn't see anything recent in a search. Thanks.
