My apologies in advance. I'm sure this has been covered in here before but my ability to use the search function seems to be minimal at best (yes - its a personal problem!) We're staying at the MGM Grand in a few weeks for the first time. We had a room at PH booked, but got an offer (1st ever) for 3 comp nights, plus pretty cheap for the rest of the week so we switched. Can we use the aiport check-in for a comped offer? Are the lines shorter at McCarren than they would be at the MGM (we're arriving around 10:30 AM)? Are the odds better or worse for the $20 trick?? I also noticed that they have shuttle service and baggage service fron the airport. It says the shuttle is $7 per person (one way), which for 2 of us seems like it would be close to the cost of cabbing it. Does anyone know what the baggage service costs, and do they deliver to your room or just to the valet?
