Activity for Riggs18

What are some suggestions for a beach honeymoon with lots of things to do and a relatively inexpensive trip?? (For example bora bora's private bungalows are Unfortunately out of the option lol!)

The church that we have booked is beautiful and perfect but does not have a center aisle but instead has two off set aisles. Looking for suggestions on how to seat guests. We will have about 150 -200 guests.

First dance suggestions? Preferably not country music, even though I LOVE country music our wedding is more of a traditional and romantic theme.

Looking for some ideas on how to set your MOH apart but not take away from other bridesmaids.
