Agreed, other than bridge openings, which can be a real PITA, traffic in general at Regatta isn't that much worse than any other time in high season. I have seen a lot of people complaining here in February/March about bad traffic in general, so not sure that Regatta traffic itself is much worse. And restaurant reservations, except on Sunday night in Simpson Bay, OR if you have a big group, reservations are not that big a deal.
