While I was thanking the first person to reply to me a bunch more were posting! I can't keep up!
Thanks for the advice, all. My kids are young - they love the parks. My husband does too, but in the planning stages he gets really moody and always acts like he has no desire to ever go to Disney again. We just went last summer, and next summer we are going for two weeks but staying offsite and possibly not doing Disney parks at all, but other stuff.
I considered the deluxe dining because it is so rare that we get the opportunity to get the free dining for our trips, and it seemed like something to capitalize on. But - could we be there, so close, and not go to parks every day? Especially MK, with the ages of my kids?
The add-on is stumping me. With more days in the parks, we won't have time to use the waterpark option. But with fewer days in the parks so that we could use the waterparks, we would need the hoppers, too, in order to see everything. Argh! I wish there weren't so many options sometimes....
