Introduce myself and run a ceremony idea by you guys.

I'm Sarah and I'm engaged, with no date yet and we are sure it will be about 2 years before we can afford to have our wedding.

We've been together for 3 years now and we have an 8 month daughter together who will be my precious lil flower girl. (FYI, I'm a rotten speller, tend to ramble pointlessly and try my best to be honest, blunt and kind.)
Ok, so we are 'that couple'. He is a rough around the edges construction worker and I am a hippy, beach bum, stay at home mom and am full of random spontaneousness!
I've been stuck on a beach wedding for as long as I can remember, but now I'm having other, equally awesome ideas!!! What do you think of a wedding at the FL Aquarium? Exchanging vows in front of a huge tropical fish tank? My other ideas are of course, a classic sunset beach wedding, the aquarium, and the odd idea that is totally different that those two is a Disney wedding in front of the castle at night time when it's all lit up! A true fairy tale wedding! Opinions?
