WSOP events...where to stay?

[RikaKazak]

So I'm going to play events 10, 12, and 15 (if I bust first day, skip ones if they overlap) and I'm curious where to stay.

For starters I'm CHEAP! My typical vegas stay is the Excalibur or the Tropicana. But I'd like to stay closer than that to where I will be playing.

I'm assuming my events are all at the Rio....also during my "non tournament" time I'm going to play the 10/20 NL at the Bellagio.

What cheap/close by hotel would you guys recomend?
