Hello from the UK, John! It's my pleasure to welcome you to planDisney. I see you're planning on visiting Walt Disney World very soon; an excellent way to dispel any January blues!
As you're enquiring about one-day park hopper tickets, my understanding is that you will be purchasing these tickets in the U.S.A. (this option isn't available from Great Britain).
The
one-day park hopper plus option provides admission to one of your chosen parks for the day. You may hop to another theme park and/or visit one of the water parks after 2:00 p.m. (right now,
Blizzard Beach is open) on the same day.
As you expressed interest in visiting the theme parks on Monday and Blizzard beach on Tuesday, here's my suggestion. Book a Park Hopper option for Monday, starting at your must-do park (my favourite park is
Epcot - there is so much to do and explore). Using this ticket, you may also visit the other main theme parks (Magic Kingdom Park, Hollywood Studios, or Animal Kingdom Theme Park) after 2:00 p.m.
You may also book a separate
1-day water park ticket, meaning you could enjoy a full day at Blizzard Beach on Tuesday. Did you know that you can even rent a private
Polar Patio while there? Whatever your choice, I know it will be a wise one! After all, you're already on your way to the most magical place on earth.
Please download the
My Disney Experience App before heading into the parks. It's the source for many useful things in Walt Disney World, not least your electronic ticket for the day!
Have a wonderful time, John! Please let me know if I can help with anything else on your Walt Disney World adventure. Louise
