Epcot seemed OK other than Friday night. So if you do HS on a Saturday or Sunday and then head over to Epcot you should be fine.
Have you looked into getting a Tables of Wonderland card to save 20% of dining? That is what we are going to do instead of the dining plan this year.
There are a lot of detours set up but traffic does move. The buses even take different routes because of the marathon.
Thanks! I think we are going to go to Kona for breakfast and then to HS for the afternoon, and then to Epcot - I plan on it just being a very low key day with our only expectations getting on TSM and Star Tours and maybe ToT if my kiddo is interested.... The good/bad thing is with both my kiddos being so young it means unless one of the adults wants to ride alone that we skip the thrill rides. Good to know that the traffic does move, we drive, and figured regardless it is just going to take more time....
We love our TiW card! So glad they offer it to DVC now for the years that we don't end up with AP's. I loved the freedom and flexibility of it.
