Hi Susan,
Apologies if I didn't explain my answer to your
previous question clearly.
A 4-day Theme Park Ticket with the Water Park Fun & More Option would allow you admission to one theme park per day for each day of your Theme Park Ticket (4-days at the Disney Theme Parks)
PLUS 4 visits of your choice to the Disney Water Parks, ESPN Wide World of Sports Complex, Disney's Oak Trail Golf Course, Disney's Fantasia Gardens Miniature Golf Course or Disney's Winter Summerland Miniature Golf Course.
You can choose to spend your 4-days at the Disney Theme Parks and 4-Water Park Fun & More Option visits whenever you like, so long as you have used them all up within 14 days of first use.
From reading your question, it appears as though you want to use your Water Park Fun & More Option visits to go to the Disney Water Parks.
If this is the case, you would be able to visit one of the Disney Water Parks on the same 4 days that you visit the Disney Theme Parks, but you certainly do not have to do this.
You could decide to alternate your days between the Disney Theme Parks and Disney Water Parks:-
Day 1 - Magic Kingdom
Day 2 - Disney's Typhoon Lagoon Water Park
Day 3 - Epcot
Day 4 - Disney's Blizzard Beach Water Park
Day 5 - Disney's Hollywood Studios
Day 6 - Disney's Typhoon Lagoon Water Park
Day 7 - Disney's Animal Kingdom
Day 8 - Disney's Blizzard Beach Water Park
You could also decide to take a break from the parks during your stay to visit Disney Springs or enjoy your Resort hotel in which case you could use your remaining ticket entitlements on Days 9 or 10 etc.
