Here's my take on the situation. As Motherfletcher suggested, I would go for the annual pass to save $ on your room. Then, as far as Disney parks, I would have to say Epcot is our favorite & is most adult oriented. My husband & I (just the two of us) also love Magic Kingdom & MGM. Here is an idea. If you stayed at the Portifino 8/14-8/18; check out the morning of 8/18 & drive, taxi, or shuttle over to Disney; then check into a WDW resort which have great discounts at this time (check out mousesavers.com). If the room isn't ready, they will hold your luggage & you can go to the parks. Then, since you are staying at a Disney resort, you can purchase a 1 night 2 day Ultimate Park Hopper pass. This would enable you to park hop & visit more than 1 park. Since you'd be visiting in the middle of the week, it may not be quite as crowded as a weekend. You could do Magic Kingdom one day, check out the next day & have them hold your luggage & do Epcot/MGM the next day or however you want to do it. You could also decide to split your trip 3 nights at PBH & 2 nights at a Disney resort. Just a thought. Sorry so lengthy!
