I'm arriving in Melbourne on Wednesday, 4/22, 9:40 AM, and departing next day, 4/23, 11:20 AM. My original thought is to stay at the Hilton Airport using HH points, although I, also, have Marriott points.

My reason for staying the Hilton Airport is for the ease of getting to the airport on the morning of departure. I plan on taking public transport (Skybus, I presume) into the city center and spending the day and early evening (dinner) there before heading back to the Hilton. From what I've read on travel sites, the Hilton isn't great, but I figure it should be O.K. for one night.

Any comments on the hotel issue before I launch my other questions?
