I've been to Jellyrolls a few times, so I'm not a regular customer, but I do frequently stay at Boardwalk Inn, as well as Yacht Club and Beach Club. When staying at any of those resorts we tend to walk around the circumference of Crescent lake a few times each evening, so we walk right by Jelly Rolls multiple times. Jelly Rolls is always busy. People are usually lined up when the doors open. We've never not been able to get a table, but once we got the last table available and another time we had to wait 45 minutes for a table to clear. If you go right at, or soon after opening you'll get in. After that, you might have to wait for a table, but it's a nice area and there are benches to sit on and lots to look at. There are also other places nearby to grab a cocktail while you wait. Sometimes there's even a potable bar cart set up right outside. I've never noticed if it gets busier on the weekend as opposed to a weeknight like you're asking about. To me it always seems like it's hopping!
