You bought RIV points? Direct? I though you were a never-Riviera because of the restrictions.
This is exactly the analysis we went through when deciding whether to add on to BLT or not. Our prior BLT resale points were unrestricted, but if we added on, we would have had some restricted points. The delta was around $5,000 as I recall, and we did the pre-opening "tour" on a move day for a split stay. What did we get for $5000 extra (in order of importance):
1. new home resort near EP/HS
2. nonstripped contract, immediate choice of UY
3. instant gratification
3a. Booked a New Years stay in April 2019 48 hours later - with spectacular fireworks views
4. easy transportation to our second resort for our split stay
5. free FPs on a very heavy holiday week
5a. we had to go to Poly to re-sign some docs, it took about an hour, and they gave us MORE free FPs for the inconvenience
5b. some issue with FPs being pulled from the correct account and inventory (e.g. using an "all access" FP for a low priority ride in MK etc), which led to even more FPs
6. free ice cream
while some of these are tongue in cheek, the FP snafu ended up having the effect of us not waiting in line for much of anything after we bought - it felt like the equivalent of a VIP tour .... over 4-5 days. For us, we liked Riviera resort, preferred the room layout over BCV/BWV and that was already worth the extra $5000. We spent New Year's at Riviera over 2019 and 2021 and IMO it's the best resort because you can see fireworks at MK and Epcot.
