Congratulations!
It really depends on what you want: Disney Fine Art Photography offers Resort or In-park e-shoots, but there are many other photographers as well. They mostly do Resort shoots, cause Disney doesn't like it when others shoot in their parks and many photographers don't want to jeopardize the privilege to be on the preferred vendor list for weddings!
I just contacted the Roots for an e-shoot - if you use the contact form on their website, they'll send you their pricing!
Happy planning!
