Maui and Oahu are my 2 favorite Islands. Oahu is the most populated Island. There is alot of Nightlife, many nice shopping areas and of course World Famous Waikiki Beach, we always stay at the Waikiki Outrigger on the Beach which is also home of the World Famous Dukes Barefoot Bar and Grill. My kids Love to Surf and Waikiki is great for that. You can always go to North Shore to Sunset and Haleiwa if you want to get away from the bustle of Waikiki and Honolulu. There is alot to do or Not do if you so chose on Oahu! Aloha! Neither Island is better than the other, Maui and Oahu are two different Islands it just depends on what you're looking for in a vacation!
