Well said. I was going to give his thread some time, since a theoretical exercise of "how can one ride the most rides while spending the least time in line" is a valid theoretical question. The Day 1 / arrival day that he drew up is an example. Yes, one would conclude, that as a result of FP+, arrival days can be VERY effective. Because you hit up the parks for a short time but still get to use 3 FPs.
Now of course the NEXT day has yet to be seen.
In your calculation above, Smith, you only quote the AP price. But Lake has to consider that he's bearing a $109 off-site hotel cost, per day. Plus gas and food for so long. So really, his basis is not $600 or whatever for the AP, rather $600+$109xD, where D is the number of days he's staying. 28 days, that's $3652 for 84 rides, or $43 per ride.
This would not be considered "effective" to most. I.e. to DRIVE to a park, park there, take the boat to the Kigndom, ride 3 things, then... LEAVE. After being in the park for less than 3 hours, take the boat back, drive home, and repeat for 28 days. There is so much inefficiency there. Right off, I could surmise that one could EASILY ride 12 rides in a day. So that's 1/4 of the days necessary. Now, $600+$109xD is only $1363. Much less spent on the same number of rides. Waiting in some lines was necessary, for an hour here, an hour there, but 24 hours a day for the other 21 days (504 HOURS) were cut out of his vacation / life commitment to the plan. Surely even if he waited an hour each for the extra 9 hours per day, this is still ahead of the game.
But, I was going to let him play out the next few days just to see where he was going w it. Why not?
I think what we'd conclude, is that doing only 3 rides per day for 28 days is a complete waste. But, I'll defer so that he can demonstrate his ideal days.
Now if someone tours this way, as in they really do spend a month in Florida (I wish I could!) then sure, going daily to the parks will give you new FPs each day, which is great. But one could not make the financial / mathematical case that "if you typically stay a week and ride 84 rides in a trip via 12 rides per day, you should switch to staying 28 days because it will save you money by riding only 3 rides per day". I was going to see how he came to some definitive conclusion.
