Sorry, I only just waw this thread. You might get a few more responses if you put it in the 'Trip Planning' or in the 'Honeymoon' (a sub-board of the 'Trip Planning') boards. That way your post will show on the front page!
I'll be going on my honeymoon in April and it will both of our first times staying on property. There is lots to do but neither of us are really the romantic type so things like carriage rides are out. We will however be eating at some of the nicest restaurants, spending money on things like the boat hire for illuminations, surfing lessons etc. Basically anything we want to do but wouldn't normally because of the cost. If a pirates and princess party is going on whilst your there you should look at getting tickets. I've heard its a great night (we will be going!)
Speaking of the cost, have you considered using Disneys Honeymoon Registry? We have signed up for it and it seems pretty good. With any luck most of our meals will be paid for through that (plus you get a special honeymoon gift card which, I've heard, will often get you a free desert!). PM me if you have any questions about it.
Another thing we will (hopefully) be doing is having the 'Romantic Photo Session' at the Magic Kingdom. This, as far as I can tell, will give you a set of photos in the Magic Kingdom beore the park opens so there will be some great shots. It's a little expensive but a really nice memory. We will also be using the photopass as often as possible.
A trip to the beach at the Poly is definatly on the cards (thats about as romantic as we get) and we have planned meals at the california grill during the fireworks.
If you want to book meals I suggest you do it right now! I book all of mine 180 days in advance (thank you to all the adive on this forum!) and getting the times we wanted was still a little tricky.
Hope that helps
