I got fooled when I booked. First, I remembered new places being built on the lake side of Route 50, the main street through South Lake Tahoe and Stateline. When I used Travelocity to do my bookings, their map showed the Days Inn on the lake side and the blurb on the motel tied the location to the Marie Calender''s restaurant - which is also on the lake side. Unfortunately, Day''s Inn is across the street. Holiday Inn Express, Travelodge, Best Western - these are the newer places you want to check out.
Days Inn has thin walls between rooms, which may not be a problem in the winter when the heat is on full or during summer when you might run the a/c. Spring, when all systems are off allows you to hear everything going on next door.
Days Inn makes a big deal about its continental breakfast but it consists of coffee (no cream or milk, just that dust stuff), an orange flavored juice-like beverage and doughnuts.
All in all, for real skiers - the people who hit the mountain at opening, ski all day, shower, eat dinner, then crash - the Days Inn is acceptable... but there are so many nicer choices available. Go somewhere else.
Bookings are tight Friday and Saturday nights, but you should be able to take your pick of places any other nights during March.
