Hello Emily and welcome to the Disney Parks Moms Panel.
It's always a joy for me to offer another lovely Guest from the United Kingdom assistance with their jolly holiday plans to visit the magic of Walt Disney World Resort, but this is especially so when it's going to be part of their honeymoon.
My own family is right in the midst of planning a wedding so I can totally relate to how excited you and your fiancé must be feeling about your nuptials in 2019 and to have a
honeymoon at Walt Disney World Resort is just the icing on the cake!
Guests like you and I from the United Kingdom benefit from the UK exclusive
Ultimate Tickets which offer unbeatable value for money by giving
unlimited access to all 4 Disney Theme Parks, 2 Water Parks, ESPN Wide World of Sports and more besides.
Although Disney Theme Park ticket prices have not yet been released for 2019, I can share that at present 2018 Ultimate Tickets can be purchased for 7, 14 or 21 days and for a limited time the 14 day Ultimate Ticket currently is on offer for the price of 7 (terms and conditions apply)
As an alternative you may wish to consider
Theme Park Tickets from Disney.go.com which can be purchased in single or multiple days for entrance to 1 Disney Park at a time or Guests have the option to choose to add Park Hopper or Park Hopper Plus Options to best suit their needs.
In addition I thought you may find this
Coming to Walt Disney World Resort to be an extra useful resource for your 2019 honeymoon plans.
Have a great Disney day ~ Jane
