We've traded to the
Bay Club Waikoloa (Big Island, Nov 2002) and
Wyndham's Bali Hai (Kauai, Feb 2009) through RCI. We've also traded into or booked on cash through II at
Waikoloa Colony Villas (Big Island, July 2008) and the
Makaha Resort and Golf Club (Oahu Feb 2008). We've enjoyed other HI stays in properties we own directly through
Worldmark the Club.
I love the Waikoloa complex and both of the properties we visited. Lots to do/see if you are willing to walk the large property. A car is a must for reaching most HI activities.
Kauai is lovely -- but for our next visit we'll look for a resort located, ideally, between Poipu and Kapaa for a better location. The Wyndham properties in Princeville, in our opinion, were too far from most attractions other than visiting Hanalei, Kilauea Lighthouse/Bird Sanctuary which we would have preferred as day trips.
Makaha was a complete surprise in every respect (starting with a very last-minute booking less than 6 days from travel). The resort room was a disappointment but we really loved the property. The location is a bit remote, the general area considered "iffy" for tourist travel but we thoroughly enjoyed the secluded beaches scattered along the very north east (?) end of the main road. We remember this unexpected trip with great fondness.
