Do Junior Suites count as suites? I seem to recall a post a while back (maybe by one of the MC's) stating that Junior Suites are not considered suites and that a hotel should upgrade you to them if they are available, but I cannot remember for sure.

That said, I seem to have had luck with Marriott lately as I got the Presidential Suite at the New York Downtown property, am writing this from a suite at the Renaissance Providence, and have already been upgraded to a suite at the Renaissance Boston for a stay on Monday.
