Wishing you an early Happy Anniversary!
I'd you'd really like to splurge, you might like
A Magical Experience from Disney or perhaps one of these many true love items found
here.
However, you could also opt for more simple, less costly options such as purchasing a bottle of champagne to sip along the shores of the Polynesian Resort while watching the fireworks (there are perfect hammocks to cuddle up on) or one of the movies under the stars (check with Guest Services at your resort about times & availability).
Similarly, you could might find a carriage ride just as charming; Disney Mom Suzannah does a great job describing them
here or if you are more active
bicycles can be rented throughout much of WDW. And did you know there are three
spas to relax and unwind?
I've also worked with a non-Disney company www.giftsofalifetime.com for surprises for both my husband and children that were magically special.
Have a magical trip!
