Recently received a crowd calendar update for my vacation dates. If I optimize my personalized plans now, will I see a change in the order of attractions and/or wait times? Change was not drastic...only a point more or less on several days.
If you want to keep the order, then Evaluate, do not Optimise.
Or take a copy of your plan first (there's an option to do this) so you can revert if you don't like the new one.
I rarely use Optimise, definitely an Evaluate gal!
There could be significant changes in attraction order, or there could be no change. As mentioned above, if you particularly like your current attraction order, then you might want to make a copy of your plan before re-optimizing.
