Hi Terry and Karen. Like others, I'll say congratulations and welcome! I'm not attending the rally and while I'm far from the most knowledgeable folks on this site, I have a 2014 Marathon and if you have an easy question, I may be able to provide an answer.
Speaking of rallies, make sure you plan on attending the Prevost Expo in West Palm Beach in February. It's a stone's throw from Port St. Lucie and it's a wonderful event.
