Only in upfront costs. In a full calculation of value, redemption value, lost opportunity cost, etc... Beach Club re-sale is far more expensive than Riviera.
This is oversimplification, but very very generally... Imagine you're buying 200 points, to use for 19 years (until 2042 expiration):
At incentivized 188 per point, plus closing, you would pay about $39,000 for Riviera.
August 2022 re-sale of Beach Club was reported at $174 per point. With closing costs, about $36,000.
Now, let's do 19 years of ownership, using 2022 dollars:
Beach Club: $28,637 in dues
Riviera: $31,859 in dues
Now, let's do redeemed value in 2042 (re-sale value):
Beach Club -- $0 return
Riviera (using current 2022 dollars): Approximate $28,000 return
Total cost through 2042: Beach Club: $64,637
Riviera: $42,859
Thus, over the same period of time, Riviera works out to be $20,000 cheaper than Beach Club. It isn't even close.
This is why the 2042 resorts tend to be such bad value, and so overpriced.
(The least overpriced is Boulder Ridge, but even Boulder Ridge works out to about $14,000 more expensive than Riviera).
Now, this is a bit of oversimplification. If we add in lost opportunity costs, it narrows the difference slightly, but not nearly enough to wipe it out. Then there are unknowns. But this is really the best estimate based on known factors. (unknown, a tornado could hit Beach Club wiping out its value... global warming could make Orlando unlivable, destroying all DVC value starting in 2035, etc).
