Welcome to planDisney, Jacinta! Thanks so much for coming to us with your question today.
I'm sorry to hear that you've got some illness in your family that might throw a wrench in your travel plans. These things happen, and it's a great idea to get all the information that you can so you can make the best decision going forward. Jacinta, the best thing for you to do right now is
call Disney Resort Hotel Reservations. They will be able to walk you through all of your options, give you the timeframe that you have to make a decision, and help you work out what is best for your family. It's a good idea to call as soon as you can, so you have the greatest number of options available to you as well as the benefit of as much time as possible to make your final decision.
I know it can be tough when a last-minute hiccup alters your carefully made travel plans, but prioritizing your family's health is always the best choice. I hope that everything works out and you're able to make it on your upcoming vacation, but if you end up needing to reschedule, Mickey Mouse will be waiting to welcome you back whenever you're ready.
Have a magical day, Jacinta!
