Actually I do not think you have to worry....right now they are mainly doing room rennovations (new room decor....nothing like moving walls or anything) and they are doing the south wing a section at a time. They are also working on the 10th floor of the tower but I think that is supposed to be open by your trip dates. They are just moving what used to be the tower club lounge up on 12 down to 10 and the tower club rooms will be on 10 also. The good news is none of the rumored big moves (expanding chef Mickeys, moving concourse steakhouse and the arcade, etc) are underway at present and no one has really even confirmed that they are going to happen at all.
The new room decor is lovely....we are going in Nov and would love a new room, however I was kind of fond of the old decor as well....so either way is fine with me. I don't think there is anything going on that will interfere with your magical stay at all!!
Happy honeymoon.
