That type of dress would be perfect for your venues and the feel you're trying to go for in the wedding

Have you started shopping yet? Dress shopping is very exciting, but can also be very overwhelming.
For the parasols you should check out this web site:
http://www.asianideas.com/ I used them for my wedding (one of my signature pictures shows our parasols) and they were really reasonable priced. Although, I am sure in LA you could probably get them locally a lot easier than I could here in MI.
Port Orleans Riverside is our favorite resort, we stay there on most trips. It is a great place to stay, but because of its size you should definitely request a certain building depending on what you want to be close to during your stay. The mansion are more romantic and secluded, but you can still get one close to a bus stop. We usually request Alligator Bayou buildings 14 or 15 because we like to be closer to the main building with the food court and restaurant plus it is close to the first bus stop. Another great thing about the hotel are all the pools spread throughout the resort.
