I would add the following to Granny's response:
* We actually COULD see the EWP from our villa (#4507, a dedicated 2 br). Every night as we got our smaller ones ready for bed, we opened our balcony door and listened and watched as the parade went by! If you take the sit on beach route, the only extra thing I would advise is a bit of repellent -- sometimes a pocket of mosquitos can find your area... on the whole, we found very few "bug" problems at VWL/WL -- better than our own backyards, probably! But at night on the dock or beach area, well, what can you say, it's a lake and they are mosquitos -- the two sorta coexist!
* We found busses very punctual. One funny thing, tho' -- there is usually a CM "bus stop greeter" at the WL bus stop. As we came up to the stop one day, we watched as the Epcot bus pulled away. SOon after, some folks came up and the CM asked where they were headed. "Epcot", they said proudly. "Oh," said the CM, "there should be a bus for that in just 15 minutes or so -- have a seat." I asked her quietly, "Uh, didn't the Epcot bus just go by?" "Yes,"she whispered back, "but I can't tell THEM that. It would ruin their whole day -- so we just tell them when the next bus is coming!!"
* We don't have one "gotta do"... we do have several! Among them are: eat at WC, sit in hot tub at WL pool at night (especially while geyser erupts or light parade is out on water playing music...), watch / feed ducks on the dock (they have duck food in dispensers...by luck, we also had the otters show up twice and they are just so darn cute!!) take the boat around in circles (it's a peaceful ride and the view of WL as you approach from Fort Wilderness is awesome!) and lastly, we did "flag family" which was, as my SIL said, "way cool". We were on top of the lodge overlooking the Walt's kingdom, so to speak. Best of all, the CMs give you their undivided attention and answer any and all sorts of questions, Disney trivia, rumors, etc. Up to 6 people can go, it's at 8:15 am, you raise the flags (US, Florida, Disney, WL), they give you a certificate and you can take all the pics you want... My one regret is that we did not take my two older sons up there, ages 6 and 7 (the CM who scheduled it for me made it sound like such a daunting climb -- must be of sound health, able to climb lots and lots of stairs, etc. In truth, it was a piece of cake.) They would have enjoyed the view, I think, and it seemed fairly safe up there (sturdy wall all the way around).
One thing I DIDN'T do (but wanted to -- must do next trip!) is drink a raspberry lemonade from the pool bar... the description sounded heavenly! Oh well... next time!
