My hotel, the Hyatt Regency at Waikiki Beach. It was very swank. And it was right across the beach which was even better! I was on the 36th floor which is very near the top... and kinda scary when you're looking down.
Shopping was all in an easy walking distance from the International Marketplace to the King's Village. There was also a ton of ramen and Japanese restaurants around the place which was pretty cool.
