One thing I will tell you is not to try to cram too much into your day (as far as attractions go). When I've planned things down to the minute, things always got crazy, (IE, longer lines which makes us late to our ADR and kind of made our surprise anniversary trip nuts), but when we went when we got married, we took our time and did what we wanted to do at the moment and really enjoyed ourselves. I'm planning for us to go back in October for Food and Wine & his Bday, and that's what I'm going to do, wing it.
You're staying at a great resort, so try to enjoy it. The grounds are beautiful and vast, take an afternoon or evening to enjoy it and take a rest from the parks. They have a carriage ride at Riverside, which is just a short walk away, at a small cost. At Riverside there is also a table service restaurant and a nice lounge. There is also a boat ride from either PO resort that takes you to Downtown Disney and I hear it is a nice ride.
You can ride most of the rides anytime, but this is your only honeymoon, so don't forget to take some time and get your pictures taken. I didn't get any and I regret it. There are PhotoPass people everywhere and if you ask, they'll take your picture with your camera as well. If the price tag for pre-ordering a PhotoPass CD is too much, ask around these boards. There is almost always someone looking to split the cost, order the CD, combine yours with theirs (and maybe others) and send you a copy. I did this on our anniversary and it worked out great (was split four ways so I only paid $25!). Also, on that note. Photopass also offers resort photo sessions at a few of their resorts for a decent price. If you share the cost of the CD(s) (which has unlimited pictures) three ways and get the photopass resort photo session, you're looking at less than $100.
Hope that helps! congrats!!
