Unfortunately Wednesday WindDown will not be on for 2018... mainly due to ongoing construction... the park will resume full events scheduling in 2019, when construction is scheduled to complete.
I believe Wind down runs June thru September. I am here now and yes there is still some construction going on and it doesn't seem to be affecting anything going on in the park.
I was there last week, and I seem to remember some construction still going on. It wasn't intrusive though. The garden and the fountain were pretty and open for business.
I am not entirely sure. But you can always keep an eye kut on their website.
