If you want to learn the Hyatt system, the best place is here on TUG, right here in this forum, honestly.
As for Hyatt Kaanapali, go ahead and fall in love with it. What's not to love? It's a great spot in a great place. Folks who own there have the luxury of being assured, every year, that they will have their unit to stay in. The other Hyatt owners, like me, who trade in, don't have that security of knowing what week we will get, or what floor band we will be assigned to (low, mid, high). But the Hyatt Kaanapali MFs are pretty high compared to the rest of the system, so I am good with paying $1650 in MFs for my diamond week in Sedona and trading in when I can, knowing that the owners who are staying in their units are paying, what, $3600 or $3,800 in MFs per year. I'm not knocking it, Kaanapali owners get something very valuable that I do not -- certainty.
When you get back, tell us how it all went, and everyone here will be happy to chat with you about different ownership strategies!!
