Omg yes, I'm so happy you're staying at a deluxe resort <3 It's perfect for a honeymoon and if you're gonna do Disney, do Disney!
There is so much! I hope you're having a decently long honeymoon because I think I would have a stroke trying to plan a shorter Disney trip haha. I would say... if you're a shopaholic like me, don't forget about Disney Springs. It's a perfect little day trip for if you maybe only have a half day on arrival and you don't feel like hanging around the resort, or if you've finished a park in the afternoon (easy to do at Hollywood Studios and Animal Kingdom) and you want to keep exploring in the evening. The restaurants there are perfect for more mature, romantic evenings while still feeling immersed in Disney.
Please post lots of pictures of your mouse ears and food afterwards!!! I hope your trip is super magical~
I totally forgot to answer this! My dream honeymoon is Walt Disney World but I think there's a fat chance my partner is going to find it very romantic since he's not a Disney or big crowds kind of person. Instead, I think Austria would be very romantic~. The alps, the architecture, the cute little villages <3
