Update to this thread! So my six year old and I parked at Buckeye and Ohio, and rode over to the park! Crossing over the case bridge, we didn’t have any issues with scaffolding, but there were a couple pieces of equipment in the way that were easy to get around. Beware the smell from the Wharf when it’s 100 degrees though… Hahahaaa… After that we rode through Benneker park, and down the sidewalks on Maine, around the corner onto M Street. While I wouldn’t recommend it on a road bike, there were plenty of opportunities to do small jumps and bunny hops on our mountain bikes 
Do not waste your time locking up your bike outside, USE THE VALET!!! The guys were very courteous and friendly, and other than a nice tip, cost nothing!!
Thanks again for the input!!!
