Michael, I can speak from "current" experience as I am writing this as I sit in the "
Inn at Amish Acres" which is conveniently located within a short distance to the Newmar campus.
I was placed over here for several days initially out of necessity,as the coach heat was NOT working and then I simply chose to stay over here for the duration my service visit.
If you do choose to stay in the coach, you must vacate the coach by 0600 when the tech arrives and then you are brought the coach back around 2:00 when they're done for the day.
In my case at least,it was more important for me to allow them the uninterrupted access to the coach, in order that they NOT have to take the time out of the day to put things back in order...With them having the coach they're able to leave a job unfinished one day and get right back at it the next morning....
I would NEVER worry about leaving anything in any lot at either Newmar or the Inn,as I've not seen anything to suggest that anyone worries about it.
Several of the RV delivery drivers leave their rigs here in the side lot of the Inn overnight and there's never an issue I've seen.
As far as things to do,there are not many things to do here in Nappanee,other than the Amish Acres "Round Barn Theater",where for instance the show "High School Musical" opens here the middle of May. There are different shows that run on a schedule which can be found at the aforementioned hyperlink.
Shipshewana is a great flea market in season,there's the RV Museum and also a Camping World in nearby Elkhart, and even a Wal-Mart in Goshen...
As far as factory tours,don't miss the Newmar Tour,but you are literally surrounded in this County by RV manufacturers....You can see Louise in the general service waiting area and she has a desk FULL of maps and things to do.
You'll find everything to eat right here in Nappanee,from very good Chinese,Italian and even Steaks and Seafood...
There are several watering holes with both smoking and non-smoking areas and even a small one screen theater in Nappanee.
To do any "serious" movie viewing you'll end up in Goshen...
If it's laundry you're needing to do,I've referenced the laundromat locations in a post at the top of the Newmar Forum.
$1.75 per wash load and .25 for 9 minutes to dry.
There's a CVS pharmacy in town,a Chase Bank and even a pretty nice hardware store.
Sorry this is long,hope it helps..
