Hello Denise and thanks for bringing such a great question to us here at the Disney Parks Moms Panel.
Firstly I have to say that in my own personal opinion it sure is worth it to reserve either a Getaway Glen Umbrella at
Disney's Typhoon Lagoon Water Park or a Lodge Umbrella at
Disney's Blizzard Beach Water Park and in past yEars my husband and I have even treated our family to the luxury & convenience of a Beachcomber Shack at Typhoon Lagoon too!
With so many magical
Special Offers, Deals & Discounts to choose from I can understand that it's tricky making vacation arrangements so far in advance for August 2019 especially when family members have recently undertaken new employment but I have good news in that
Disney Theme Park Tickets with Park Hopper Plus Option can at present have the dates changed prior to midnight (ET) on the day before the tickets 1st valid date of use.
I'm also happy to share there is no fee to make these changes but of course additional costs may apply if altered for dates with higher ticket prices. It may also be useful to know that no refund or credits are given for changes from dates with higher prices to dates with lesser pricing.
Disney Theme Park Tickets with Park Hopper Plus Option really are a smart choice as they do indeed provide access to all 4 Disney Theme Parks plus 2 Waters Parks (based on your length of ticket), ESPN Wide World of Sports Complex (conditions apply) plus 1 round of miniature golf per day before 4pm at either Disney's Fantasia Gardens Miniature Golf Course or Disney's Winter Summerland Miniature Golf Course & more...
