I heard these comments prior to buying Wyndham, but frankly have never had to actually pay one penny extra except the credit pool charge. That fee is $39, which I am
happy to pay to get three full years of use from up to 100% of my annual points!
The use of "reservation transactions" is, as Dean stated, a "pay to play" fee. If you make a normal number of reservations and watch what you are doing, you should never have to pay a fee. But if you are one of those people who ties up MS with constant bookings and cancellations, you will pay for the privilege. If DVC had something like this, I suspect you would see far less speculative booking and probably zero reservation "walking."
