Hi, I am a Dreams bride.
The time we actually chose to go is more expensive that the fall, but our date worked for those important people in our lives that we really wanted there. So that is one thing to consider. I think we have about the same number of people.
I looked at a couple of hotels close to Dreams for options, but honestly, they would be paying more once you include food and drink.
I suggest working with a travel agent to try to find the price points you are looking for.
Keep in mind when contacting Dreams they may take a while to respond, but they will. They have weddings there several days of the week and are pretty busy.
I think there you can have the reception (if you choose to have one), in the garden, ballroom, terrace, spa area or on the beach.
Good luck and let us know how if you have any more questions
