Definitely go for a long weekend! You are so lucky that Disney World is only 7 hours away, and trust me, when it's farther away, you will wish you had just taken all of those weekend trips, especially with APs! Don't bother with Seaworld if you aren't loving it. A short weekend should be a break, so only do the things you love! (Get lots of FP and enjoy some of the side shows and shops with AC if you want to stay in the parks during the afternoons, otherwise, go for a swim or nap and enjoy the park later that night! I'd say stay at a value resort. Maybe try a new one where you haven't stayed before because if you hate it, you are not there long, and you won't waste a longer trip in the same place. Also, theoretically, you could stretch your dollars so that you could do another Disney stay sooner. I'd go toward the end of July during the second value season, and then go again in Sept, or maybe October for the Halloween Party (or do both! and just make regular long weekends at Disney part of your life while you can)! The best part about planning a few long weekends is that it can relieve you from having to see/do everything each time. Focus on a park or two and a few memorable experiences. In the heat, skip commando style and maybe save it for the cooler months (then you could do one of those ultimate trips where you try to fit in everything in a park in a single day just to see if you can, and then relax the rest of the trip, but summer is too hot for that). Do a character meal or dinner show to immerse yourself in the Disney experience without having to fight long lines. Skip the meal plan on such a short trip, unless you get a discount on it. Have fun! (Even 2 days would be worth it, but just pick a few special things to do because otherwise you will be dead at the end).
