To avoid humidity do not go in June or July. As far as places to stay there are many rental condo's! On the weekends the lake can be a little crazy "washing machine effect" do to its high bluffs and many cruisers! The most boat traffic is around party cove, grand glaze bridge area, and by the bars/restaurants...the good thing is you can avoid the traffic because the lake is HUGE and has large coves to hang out in. If you want the action stay around the 15mm or lower.....want to see a little action but mostly family fun the mid 20's mm will do just fine!
