My wife and I spent a week on oahu. We met the great life tour ladies at our hotel presentation. We went through LeAnn mostly, she is great. They were all a great help to us. They get you the best tour guides who are very knowledgeable about island and pearl harbor tour. We will be sure to use them again.
Oahu has many activities to choose from but you can not miss the swim with the dolphins program there. My wife and I were on our honeymoon and did the royal dolphin swim there. We had a blast.
Catamaran sail and snorkel was cool. No dolphins, but we had a great time and were well treated. We recommend it to all!
