You are a DLR expert! I'm very sorry to hear about the spider bite, and hope it gets better soon. I'm glad that you otherwise had a great trip.
As far as your take on FP+, I enjoyed reading it and have nothing to criticize; however, based on our 2 FP+ trips, I would say that you had really good luck. We have not had those same type experiences. We had a DL trip in between our 2 WDW FP+ trips, and it was wonderful to be back in the land of FP and total flexibility. I can certainly see how if you had late sleepers and only cared about 1 of the tier 1 attractions in the tiered parks, it would be nice to have 3 guaranteed FP+ in advance. I will say that I do enjoy not having to make the morning park opening run to get the top priority FP (particularly TSM and Soarin), and that you can often get a decent 4th FP+ in MK. Other than that, based on our experiences, we do not like FP+ at all. We feel that we lose a lot of flexibility, that we run around in a hurry to get to places more, tiers are very limiting and a big problem for us, we have dealt with several annoying glitches; and we have experienced increased standby lines and things we are used to being walk on in the afternoons have had half hour lines (including Figment, Nemo, Small World, Haunted Mansion and Pirates among others). Typically, we go during a week when the crowd levels are listed as 5-7. Usually it is 6 and 7 on the weekends, and 5 most of the weekdays.
