OT: For all tickets with the water park, fun, sports, plus option and a finite number of visits:
Blizzard Beach in the morning, Typhoon Lagoon in the afternoon, that's all -- Consumes no days and two visits with or without hopping on the ticket.
Blizzard Beach in the morning, Magic Kingdom in the afternoon, that's all -- Consumes one day and one visit with or without hopping.
(hypothetical and theoretical only, to date) Horseback riding, two visits -- Doing it once requires/consumes two visits.
Water park, etc. activities may be done in any order, combination, or repetition up to the number of visits on your ticket.
You can leave and return to the same place later in the day without consuming another visit although for some of the activities such as the golf you may do the activity only once per day.
Not sure whether theme park tickets with water parks and no hopping are still being sold.
