I recently got married at the Palace on June 27, 2015. We had a beach ceremony, cocktail hour on the beach, and then the reception at the Mariachi Grille. Everything was amazing!
To answer your question about the getting ready... My fiancé and groomsmen all ended up getting ready in our room and my bridesmaids and I got ready in my mother's room (which was a floor above us) since that is where I was keeping my dress anyway. It worked out well with the photographer. She went to do the groom getting ready, and then came to us before the ceremony to take "Getting ready" pictures.
Please let me know if you have any questions and I can try to answer them the best I can!
