I will be returning to the US from Buenos Aires using UA 861 which departs at 2205. I will flying first class.

As I will most probably have to check out of my hotel about noon on my day of travel I am considering what to do between noon and check-in time and I would be grateful for the following information:

1. What time does the UA check-in counter at EZE open - or is it open all day?
2. Is the Red Carpet Club (or similar) on the land side or air side?
3. Is EZE an OK place to wait for four or five hours prio to check-in?
4. Is there a nearby hotel which offers a Day rate?

I would welcome all suggestions/advice
