@Mike R. @John Lee I have a vacation rental in Cathedral City that does similar numbers as your big bear place and are in for 230k. After a couple years we are over 60k gross on over 200 days rented. Palm Springs mid century's do very well. It is the most sought after property (which the price tag reflects as well). I think the overal ROI will rival your big bear place.
As far as what renters are looking for in my opinion you have to have a pool. A place with out a pool will not rent in the summer. A place with a pool rents out every weekend in the summer.
The city council vote is concerning and something to consider, but it is such a big part of the economy out there, I don't personally see vacation rentals going away.
John is pretty right on with the high season, but I would not really call summer slow, since we rent out every weekend in the 110 degree heat (not sure why any one goes there this time of year!) My occupancy rate is 58%, and I use 50% when analyzing new properties, since the first year is the slowest building up reviews and repeat guests.
