We have to pick up a couple flying in from California via Southwest on Tuesday before Thanksgiving. They are scheduled to arrive around 4. They have a layover in Phoenix and I really doubt they will be on time. Need suggestions/instructions on picking them up. We should be at MGM at that time and will probably send one of our party to pick them up. We are staying at a pool home not on property. I know it would probably be easier for them to just get a towncar or something but I am not in the posiition to insist on that. Any help will be appreciated.
