We enjoyed our 1 night stay at the Holiday Inn Express South Lake Tahoe, room 270 on third floor. The staff was friendly, the room was clean, bright, and recently updated, and the pool/spa/sauna was well situated, warm, and clean. Instantly hot water in the roomy bathroom, great tasting water from the faucet, mini fridge was nice and cold, bathroom had nice fixtures and beautiful granite countertop, slate? floor.
Heavenly Gondola, shopping, and restaurants were within short walking distance. My 8 year old daughter befriended English children her age in the pool--Sophia says "Hello" Rebecca and Carl! Loved the diversity of travelers there during our stay.
Only negative, Lake access nearby cost $20 for the day, and we did not know whether it was free to us as hotel guests. Make sure to ask the hotel, otherwise the nice short walk to the Lake will result in disappointment if you don't want to pay to put toes in the water.
