I can't stress enough that you should enjoy the Aman lifestyle! Especially on your honeymoon. Amanusa is NOT beach front but they have a beach area just a shuttle away. Amanusa was my first Aman adventure perhaps thats why it remains my favorite thus far! Many others to choose from!

If you choose Aman make sure you put honeymoon in your reservation. Aman does a great job responding to and treating each guest in a special way. Aman wants you to feel at "home" and they have succeeded. You might not see Aman in every top 100 list, but thats a good thing. Although the Aman lifestyle is spreading fast!
