You will be paying 300,000 times $6.50/per 1,000 points (middle of the road MFs and CWP for Wyndham 1,000 points YEARLY) is $1950 in 2016.
With a 5% MF increase, another $2050 for MFs in 2017.
NOW, add in EXCHANGE fees for your 600K of Wyndham points in RCI ... 105K of points for a 1bdr HIGH season (not Prime season as you are doing this last minute), would get you 5 1bdr units with exchange company fees of 5 time $229 ==> $1145.
So for 5 weeks of Wyndham resort vacationing over 2 years, MFs ($1950 + $2015) plus exchange fees ($1145) is $5145.
But here is the kicker ... you cancel an exchange, you totally LOSE the $229 exchange fee and may lose some/all of the points. You cancel an Wyndham reservation, you MIGHT have to pay for an additional Reservation Transaction (call in is $50(?)/online is $40(?)) but you would retain your Wyndham points (if cancelled 15 days or MORE before the check in date.)
With Wyndham reservations, you can book 7 or fewer nights ... pay a few Housekeeping Credits and/or Reservation Transactions. As you are a resale buyer with Wyndham, your RCI account is a Weeks ONLY account ... not a RCI Points account which lets you book under 7 nights.
RCI is not the same as Wyndham. You will spend MORE time looking for vacations THAT YOU CAN TAKE for 7 NIGHTS.. spend MORE money for those vacations .. be LOCKED into those vacations unless you buy RCI Insurance .. etc. RCI worked BEST when you plan way in advance and put in ONGOING searches.
