agree, corner rooms are nice, spacious, comfortable... just so you know: afaik, the "suites" are "junior suites" with a regular room and a very separate living room, with a pull-down murphy bed in the living room. in my stays there (would guess 100 or so) i've never actually had a room that i would consider a true suite, e.g., with a dining room, etc., so can't say whether or not they actually have a suite like that.
fwiw, i wouldn't blow 10k points on it for these reasons:
1) as a platinum, i generally always got a corner room on a higher floor...
2) the junior suites are nice, but not that special. and
3) the regular rooms aren't generally bad, although can be small (not nyc small though)
ymmv.
