Hello,
I would settle into the hotel and possibly have the kids swim for awhile before dinner. You can take a bus to DD but, just as a warning....the construction down there right now is pretty crazy. Traffic (both people and cars) are wall to wall and it will take quite awhile to get from point A to B.
They drop you off at the Marketplace end where the Earl of Sandwich shop is and the Once Upon a Toy shop. And of course Ghiradellis!
Then you can either walk to DDWS or take a nice boat ride to where you can find, Disneyquest, Splitsville, LaNouba and House of Blues
Splitsville is lots of fun with bowling and amazing food choices right at your lane. Weekdays before 4:00 pm bowling is $15.00 for 1.5 hours of lane time. After 4 it is $20.00. If you don't want to bowl, but still want to dine, there is a separate check in area for that. We have bowled and dined there and the food is really good. Good size portions for a decent price.
There is a new place that opened up called The Boathouse, right near Fultons and T Rex (and the
Lego store)
They have Aquacars which are really fun to watch in the lake. I am not sure of the price, but they are available to rent.
They have done ALOT of great things at Downtown Disney and it looks great, but it is very hot during the day, this is why it is good to stop at Ghiradellis and get some ice cream. lol
There is also Planet Hollywood and the AMC theaters, where you could dine and watch a movie at the same time if you wish.
Sorry, I am like an oversize kid in a candy store when it comes to all the options at Disney!
Perhaps, go with the flow and see how everyone feels after checking in? Hard to do when there is so much to do, but rested kids and parents are always going to have more fun than stressed out parents and cranky kiddos.
