Christina - I too had a few trials done with my hair and actually similar styles too. But none of them looked this good and I loved my hair. They also have the product for WIND - cause its windy there..LOL I say go for it, it is your special day and it is so wonderful to look and feel like a princess. The flower was real, I had ordered 2 but we used only the 1 and I think they were $10 each. Yes it did wilt by the end of the night but at that point I didn't care.. I wish I knew who did my hair. I thought I had a picture of us but it didn't work. She was really good and I was done way before my bridesmaids. I have been growing my hair out for along time so the last thing I wanted was an updo to hide the length. Even if you leave it down but have them put some curl in it is lovely. I saw that on another bride at our honeymoon resort and she looked lovely. It was simple.
If you do decide to do your own makeup. I also suggest either getting some lessons or going on the internet and looking it up for pictures. It reallky does make a difference for pictures having the right makeup. They do use MAC product so it is good quality. The only thing I wish I had brought with me is a finishing spray you can get that helps set your makeup so it lasts longer.
I did not even look at where the beach ceremony would be, I saw pictures of the Gazebo and fell in love with it instantly. So sorry I can't help you with that one, Im sure it is just as lovely.
