Alice, we like the lake too but in my opinion the better resorts are not on the lake and some like ours don't have lake view,(few exceptions).
We own at the Ridge Tahoe up the mountain fifteen minutes from the casino's and I can tell you it is great and so much to do for your family.
There are other resorts down by the casino's if this is what you like also!
A good place to check resorts with pictures and reviews are the Redweek rental/sales site. You can pick a area from So.Shore to North Shore and see what they look like and read some information about them also.
I posted when II changed from Five Star to their new rating . There are thirty resorts in Lake Tahoe and nine are rated Premier (Gold) by II.
This is just II and not Rci resorts!
Remember if you are going to be spending lots of time on the beach and swimming in the lake then a resort on the lake is great but even then many of the units sit back away from the lake.
I have been going to Lake Tahoe for many years and the one thing I found is no matter where you stay you will drive around the lake and drive to the beach area if this is what you want.
Have fun in Lake Tahoe! PHILL12
