6 weeks seems to be pretty standard for releasing park hours. Sometimes they are feeling sassy, and wait even longer. ugh.
For food, it just depends on what kind of trip we have planned. A quick trip for us would look like Mickey waffles at Carnation Cafe, and then the typical disney foods around the parks to keep something in the stomach. Turkey legs, dole whips, raspberry macarons, matterhorn macaroons, beignets, mint juleps, corn dogs, churros, and cream cheese filled pretzels. Junk. Pure, delicious junk. If its a longer trip, we will go to Blue Bayou or Cafe Orleans as well. We stop into Jolly Holiday almost every trip down Main Street. I am still experiencing different places as an adult, and trying to force myself to try different things while I'm there...I'll probably try out the famous fried chicken at the plaza this trip. My only thing is to not order things that I can get anywhere else, things like cheeseburgers or pizza. I am also making it a point to get to the Cove Bar for the first time this trip...lobster nachos and cotton candy lemonade with blue raspberry vodka on Paradise Pier is calling my name!!
I don't have an answer for the third question. I've never booked it that way, sorry!
