So hotel update. We are going with the Hilton. They finally called back and agreed to waive the parking fee as they originally said. He also said that having more than a single shuttle making mult. trips is still possibility, but it will basically depend on availability when it gets close. (i don't believe that, I think it is a done deal...) But since I doubt I would need more than 2 round trips anyway, I will just deal with that.As for the Marriot...I talked to my sister more about the convo she had with the sales lady. She was told a shuttle service is between $600 and $800. The reason is that they don't have their own service and have to use another company, so you end up with the shuttle there for you the whole night. That option is not worth it for me, but if you are expecting a ton over overnight guests I could see that possibly being worth it...and it would be nice to have them there for you, sort of "at the ready."Hope this helps!
