Hey ladies

Wedding planned for March 17, 2012. Just about a year and a half away. Obviously in the beginning stages of wedding plans. We are tossing around tons of ideas (which i'll list below) and would love any input and additional ideas you may have.
This is a budget budget wedding! My fiance and I already have a wonderful child together, (7 months) and are not looking to go into debt for the affair. I would say a budget of 5-6k for wedding and reception not counting decor and DIY projects as I will do those slowly (Luckily I have the time!)
There will be about 50-75 guets max. Some out of towners for sure as my family lives in Michigan, and much of his in nebraska.
We are not real finiky about the wheres or whats. Most important to us is an enjoyable time for our family and good music

Ideas we are considering:
- Beach wedding. Possibly renting a large vacation home on beach and hosting the small reception at the home. (assuming this is okay with the owners)
- Beach Wedding, reception at a venue near by
- Winter Park Farmer's Market Wedding. The rental is definitely in our budget... I'm just not sure how the logistics would work since the reception site would be directly next (same building) as reception site. (Do Guests just immediately move into room for drinks etc? Also logistic issues with Winter Park.. they have a Farmer's market every saturday so the venue will be occupied until 4pm. Which would require an evening wedding. But even if the wedding was 6pm... that does not allow much set up time.
- Ottis Castle St Augustine We found a lovely venue (well pictures look lovely, haven't toured it yet" that is a replica "castle" of one in Ireland. It holds about 50 people.
Any suggestions are highly appreciated!!!
