Well, I'm not sure how to tell you this, but....
...you're going to have a great vacation!!!
We decided to try something besides VWL a few years ago, and BWV was our choice for a 5 day trip. BAM!! We come home and buy a resale contract for BWV!! Yes, we liked it that much!
We now alternate between BWV and VWL trips. This year it is BWV and we are very much looking forward to it. It is very different from VWL, which is one of the reasons we really like it. Being able to walk to two parks is extremely cool, as is the choice of restaurants and activities on the Boardwalk itself. It almost feels like we have gone somewhere besides WDW because it is so different from VWL. So it helps keep WDW fresh for us while keeping VWL in the mix of places to stay.
Obviously, our BWV purchase has not diminished our love of VWL. And we will make a point of going over to WL at least once during the trip and grabbing a sandwich at Roaring Fork and eat outside, soaking up the atmosphere. Yes, it can make us a bit homesick, but mostly it just reminds us of the great time we will have there on the next trip!
Go ahead and enjoy yourself. You have many more years to enjoy VWL, and a little change of pace will be good for you!
