Do you have kids with you? If so, how old? I was just over in your neck of the woods on the Delmarva peninsula and I suspect will will start your day pretty early (flying out of BWI?) and you may be tired by the time you check into your room. That having been said, I will say that you are staying in a area that has more than enough to excite you without leaving the shadow of your hotel. People come to the Boardwalk area just to spend an evening there. I personally wouldn't overplan this evening because there are so many factors that can delay your arrival and the last thing you need to be doing is constantly checking your watch to see if you will make it on time. Just relax and enjoy everything Disney. If you can make it to Illuminations, that's great. It's only a 15 minute walk along the Boardwalk from your hotel.
