Congratulations on embarking on this journey! We started ours about 3 years ago and we are taking factory delivery in 8 days, 22 hours and 46 minutes (not that I'm counting or anything).
When I was in Nappanee in early May watching our coach being assembled I did a side trip to Goshen to the Defries Calendar Garden
. If you enjoy public gardens it's very worthwhile.
If you have the time, I would recommend doing more than one tour. You'll get a better sense of the overall speed and efficiency of assembly of these marvelous machines. They typically split the tour duties and each guide a brings little different style and content. X2 on the Monday PM tour when John Monterusso (might) lead the tour.
If you get to the tour office early you can also browse the interior selections for floor tile, back splash, countertop, and fabric choices; as well as exterior colors. It's a good opportunity to ask questions about the process of 'customizing' your coach with specials, and timeline considerations of the overall ordering process (if that's what you're thinking of doing).
As far as accommodations, many stay at Amish Acres which is walking distance to Newmar (this time of year). In May I stayed at the Olde Buffalo Inn Bed and Breakfast
is a former Amish farm house, circa 1840, renovated and converted into a 7000 square foot B & B. The provided breakfast was simply amazing and the owners are fabulous people.
Oh yeah, if you like ice cream check out Rocket Science Ice Cream Parlor
. Co-located with Rocket Science Ice Cream in Coppes Commons, 401 E. Market St. is a great deli, grocery store and other interesting shops. Or for doughnuts (and other treats) go to Rise 'n Roll Bakery
. For your morning caffeine buzz check out Coffee Cravings.
Of course you can also consult the google oracle and search for 'things to do in nappanee indiana', who knows what else you'll find!
Best of luck!
