Hi Lindy!
Sharing that joy and love of Disney with others is an awesome experience, and Disney knows just how to welcome them to their first, of hopefully many, trips to Walt Disney World. You can arrange for a special gift or floral display from
Disney Floral and Gifts. The choices are really endless, and the Disney DreamMakers at DFG will work with you to create the perfect Welcome to the Magic surprise!
On the Disney Floral Gifts website, there is a section dedicated to "Welcome to DIsney" where there are a variety of special celebration gifts that can be sent to their resort room. One of my favorites happens to be the In-Room celebrations! These are gifts that are set up in the guest rooms once they have arrived at the resort. One really special one, which I think might be perfect is the Mickey's Grand Welcome celebration. Plush Mickey and Minnie dolls await their arrival back from a theme park day with a banner on the door which says "Surprise" and complete with autograph book and pen and letter welcoming them to their WDW stay. Keep in mind that any celebration will be set up on the second day of the guest stay. This is to assure that there are no issues with the room/reservation and that the guest has arrived safely.
For more information on Disney Floral and Gifts, visit their website in the link above, or call them at (407) WDW GIFT.
Hope this helps you plan your magical vacation!
