Go out there every year that National Bowling Tournament is in Reno, including this year. I'm assuming you will have a car. About a 3 hour trip to drive around the lake. Several scenic overlooks.
Most of civilization is in and around South Lake Tahoe, CA and Stateline, NV. Harvey's and Harrah's are the two casinos, and are tied together by an underground tunnel. Hard Rock Café and Cabo Wabo (Sammy Hagars' cantina) are two of the restaurants in Harvey's. There are several boat trips available (Zepher Cove). We didn't go on one this year has we have done it in the past, plus the boats can't make it into Emerald Bay (lake level down due to drought) and they didn't lower the cost.
