I'm going to keep this simple - do the math people. We're all getting hosed here. I just stayed 6 nights in Kauai for 120,000 points plus a 30,000 upgrade to a pool room and hoped I'd get upgraded again as a Plat member (didn't happen).
Under the "enhanced program" that same stay will cost me 180,000 points NOT including any cost for an upgrade. I'm assuming the point-cost chart is based on a standard room. So for the same room for 6 nights (7 nights I would have saved even more on a per night basis under the old program) under the new program, it's going to cost me AT LEAST 50% MORE!
Personally, I like to travel when it's NOT a blackout date in order to avoid the big crowds. Many people might need to book during this time, so for them this is clearly an improvement. For the majority of us however, this is a really bad deal!
Marriott will be hurt by this and I only hope they will realize that in this environment, people will seek out the most cost-effective program. I just signed up for the Hilton Honors program and will use them until Marriott comes around. Your loss, Marriott!
