I'm resurrecting this older thread as it's the most recent one I can find on the general topic of Waikoloa resorts, and I'm not sure where better to put this.
It seems that the Waikoloa (and Oahu, for that matter) Sansei is no more. We were just there and were planning to go (probably twice) for the Sunday/Monday half-price early dinner. Sadly, this did not happen.
I realize that this is not HGVC-specific but as HGVC are the biggest presence in the area, I wanted to add this to the HGVC forum.
Cheers.
