I have a general one I apply to all my timeshares, not just HGVC. Whatever points currency value gets me a unit in the highest season at a rated (RCI Gold Crown or the II premier/elite) resort should be equal to right around $125 per bedroom per night, including MF and Exchange fees if applicable. In this case, I’ll use 9600 for a 3 bed HGVC unit. I have 2 4800 point Bay club units that cost me right around $2,500 with club fee per use.
So for me, a 3 bedroom unit is worth, at Max, barring some very special circumstances, $2500 in MF for a week’s use, a 2 bedroom should cost me no more than $1650 for a week’s use, and a 1 bedroom should have a total cost of $825 or less. We don’t book studios unless we are getting additional rooms for family to join us, but I would value that slightly less, at $500 per week. That’s my standard. My WSJ 3 bedroom pool villa exceeds that formula, but is very special, so that is the ONE exception to my usual rule.
