If you want to get waterside seating, I think it is safest to get the 11am lunch reservation, which is the first seating of the day. That usually fills the waterside tables, so 11:20am gets the second row, etc. As the day goes on, it gets all mixed up as some people eat faster than others, and then their tables get filled.
On your 60th day exactly, the 11am slot usually books up pretty quickly, and not all tables in a time slot may be offered for the package, so I would plan to be on the site right at 6am PST, and make sure you scroll PAST Blue Bayou in the alphabetical list of restaurants, and choose the Fantasmic Package from the list of restaurants (see screen shot from the app below), and then click View Available Options, and click BB Lunch first show (or whatever you want) off that list. If you just click on Blue Bayou, you are only reserving a table for the meal, not the Fantasmic Package. I would do a test run a few days before to make sure you are familiar with how to book the package at BB versus just a meal at BB.
