It should take about 15 minutes to get from the entrance of MGM to Spoodles.I have made it in just uner 10 minutes but I was speedwalking!! Now, if it's hot/humid, and since it will be August you can pretty much plan on that happening, you could take the boat. If there is a boat at the dock, with a short line, then hop on. It should stop at S/D first. You can hop off there, walk over to BW...about 5 minutes. Then, when you get to between Atlantic Dance Club and Jellyrolls, hang a right (otherwise you'll walk into the lake!) and head for Spoodles.
If you walk from MGM then take a right, into the Luna Park pool area. Head to the rear of the pool, under a covered area, with the arcade on your right, restrooms on your left. Then head across the Village Green to Spoodles. Yum!!!
