We're planning a Hawaii trip for April 2007. Tentative plan is to fly into Oahu (from Buffalo, NY) for 3 nights, then hop to the Hilton Waikoloa resort on the Big Island for 6 nights (free via Hilton Hhonors points), then hop to Maui for a 7 night Cruise on Norwegian's Pride of Aloha (mostly paid with points from Norwegia's Mastercard) before returning out of Maui back to Buffalo.
