I actually ended up finding a link for Google Customer Service and got on a support call with a rep to review my situation. There was quite a bit of back and forth and proof required to show why I wanted "temporarily closed" vs. Closed and I needed to provide a 're-opening date' to achieve this. But I was able to achieve it.
The other thing to mention is that there are two ways you can be found on Google for Business listings: 1) via Google Maps Search (google.com/maps) and 2) Google Search.
For the Google Maps Search it is not possible (I confirmed with a Google specialist) to temporarily close a location via the Maps. Google Maps requires you to be open or closed.
For Google Search, once the seasonal location is ready to re-open you have to contact them again to have "Temporarily Closed" removed from your listing.
Hope this helps.
