We stayed in Bora Bora for 10 days on our honeymoon. There wasn't much to do except relax, swim and dive which is what we wanted. The honeymoon really is a great time to just spend time with each other. However, if she is into shopping, there really wasn't much there in terms of shopping. It truly was paradise but you should be prepared for the cost as it is not cheap, especially if you are going to stay in the overwater bungalows. I don't regret going there, but it definitely put a dent in my wallet.
Congratulations on your marriage. I'm sure that you guys will have a blast whereever you decide to go. My only advice is to do it sooner rather than later. I figured I would delay the honeymoon for a few months after we got married, but I didn't realize that this until later that kinda bummed her out although she never complained. So, I ended up planning the honeymoon the week before our wedding, and we left for the honeymoon a week after the wedding. I do believe that there is something special about going on your honeymoon soon after your wedding. I know people who've been married for a year and still have not yet gone on their honeymoon as life just gets in the way...
