I think that list is a good indicator of FP priorities.
Not sure if you've seen it, but on the same website, they provide the past attendence/wait times for the last few years.

If you go down the page a bit, it shows the real wait time at 3:30pm for each day of that month. That'll give you the idea which ones are popular so you should hit them first thing in the morning, and which ones are anytime filler.
I'm not familar with DL, but I've been to WDW a few times. First 2 hours of Magic Kingdom is diffinitely different from TDL. Even the busiest time of the year, MK is pretty easy to tour in the first couple of hours, but TDL is not that easy. I think it won't be as easy but you'll probably do fine because Mid May is a slower season. The key difference between them is most people in TDL know how to take advantage of FPs and early hours.
Well, you mentioned that you will be staying at a Disney hotel, so the 15 minute early entry to the both parks will help you quite a bit for touring.
