I'm quite familiar with this area and that is absolutely a good price for Door County in the Summer. Usually, decent prices are had only around late May/early June (where it can still be cold) and October if Fall colors are lesser than usual.
There's a terrific Walmart across the street from this Best Western property for snacks or other needs. Additionally, since this property is at the top end of Sturgeon Bay, a bit closer/better jumping off point to explore the rest of Door County. I'm a fan of Lautenbach's Orchard (which is a little bit South of downtown Fish Creek, https://www.orchardcountry.com/), Macreadys (Egg Harbor, https://macreadys.com/breads), Wilson's Ice Cream (https://wilsonsicecream.com/, In Ephraim) and the Farm is a fun stop that has been there since I was a kid (http://www.thefarmindoorcounty.com/farm-fun/, in Sturgeon Bay not far from your hotel.) Of course, there's Al Johnsons (http://www.aljohnsons.com/) with the goats on the roof - prepare to wait to get in if it's a busy (or sometimes even if it's a not busy) time of year.
Enjoy your stay.
