The Master Plan includes a crescent shaped "Welcome Center" added to the front of the Convo. I believe the plan is to tuck it into/behind/below that structure.
One of the problems with this concept, is that the Convo is in a located in a 100 year flood zone.
There are all kinds of issues/restrictions trying to build there.
I would also anticipate needing to build any structure on piles.
That bumps up the cost, big time.
Once the idea of a new Ice Rink next to Ping got dropped, the most cost effective location was/is ,for a number of reasons, "punch card park".
