Hello, Rebecca!
Booking your next runDisney-cation directly through runDisney is an excellent value! Generally, they offer great rates on all categories of accommodations at select Walt Disney World® Resorts. In addition, there is generally an offer available for specially priced theme park tickets that can't be beat!
As far as upgrading and modifying your reservation once it is made, you can absolutely do that! Of course, that option will depend upon availability at the time you call.
Package details for the 2015 Disney Wine & Dine Half Marathon Weekend have yet to be released, but you can see what was available last year by visiting the
Travel Tab on the runDisney website and selecting the Disney Wine & Dine Half Marathon tab (you can also select the highlighted link). And keep on eye on that web page, it is where information will be released as we get closer to registration opening to the public on March 17th.
I hope this information is helpful, Rebecca! And thank you for your patience in my reply. I've just returned from the magic that is the Disney Princess Half Marathon Weekend.
Cheers!
Faith
