Try Gifts of a Lifetime (https://giftsofalifetime.com/). They do great work! They arrange "events" that can include a scavenger type hunt in the parks. I did one for my mom's birthday where she got a rose placed around her neck in the haunted mansion stretching room when the lights went off and she had no idea who did it. It had a clue and then each clue led to another rose and clue until the final clue (which I won't reveal) ended in her getting a cool ending with something neat related to her favorite character. And we ended the "scavenger hunt" at her favorite character's meet and greet so she could get in line for the greet. Also at the end was a piece of jewelry I gave her for her birthday. She loved it. The prize at the end of yours could be the engagement ring. They put the whole thing together and their "pixies" were awesome! It's unique and a lot of fun and something your girlfriend will probably love - especially if she's a fan of Disney!I am planning on proposing to my beautiful gf this upcoming May. Although I am usually a creative person my nerves are getting the best of me. Does anyone have some good proposal ideas for Disney World?
