Are you a Loew's club member? If you aren't, go to LoewsFirst.com and fill out the info to become a member. We were only level blue last year but were able to upgrade to club level at rpr for $35. It also list in the brochure that you can upgrade to an "executive suite-max. 3 people)" for $35 if available. (for gold members it's $35 with guaranteed availability) I'm using the AP rate for club level in July $223 ($319 with fan club) and plan to pay to upgrade to something......however upgraded we can get that still fits in what we have budgeted.
I am a Loews member and have stayed twice at HRH, once at PBH and once at The Regency in New York, but have never remembered to present my card at check-in. Consequently I've never received any upgrades to my member status.
