So I booked our dining for the week - one day at at time...

Anyway - it ended up being way easier than I had anticipated.
We decided not to do the F! Premium Package because of the food choices mostly, BUT I did see it as a choice on the app right at 9am EST so I am counting that as a win! LOL
Fri - I booked Naples for our first night (no parks).
Sat - WOC Dessert Party - 2nd Show
Sun - Blue Bayou dinner
Mon - Storyteller's Brunch
Tues - Carnation Cafe early lunch, Hearthstone dinner
Wed - decided not to book anything on our last day to have flexibility and the most park time
Planning on trying walkup at Lamplight Boardwalk. Do I need to physically go there or can I try on the app? Do I need to wait until it opens or when the park opens?
Also interested in counter service and snacks at Jolly Holiday, Pym's, Craftsman Bar and Craftsman Grill, Tienditas, and Jack Jack Cookies. I am GF, kids are not, so I have been doing my homework.
All of our previous trips to WDW I booked more dining, but this trip the kids are older (23 and 20), it's just the 3 of us for the first time, and since we are new to DLR, we wanted to maximize park time. 5 park days is the shortest Disney trip we have ever had, so we are still trying to wrap our heads around getting to try everything we are interested in and still have time to repeat favorites. Also, due to school/sports/work schedules we could only ever go to WDW in mid August, when the humidity and heat zapped all of our energy and patience. We always took a long midday break. I know DLR will be hot in June/July, but it can't possibly be as bad as WDW in August! We are staying at GCH, so taking a break should be easy.
Thank you to all of you for your help so far! I am sure I will have more questions and I will definitely keep checking in for more tips and info! Looking forward to PTN and 70th merch!
