We did a split trip last year and ended up at the beach every day. We were with our 6 year old, so the beach was better suited for us. This year we will be back and staying only at the beach (Palms). We certainly will go to the other side for several meals, etc.

I think it's a simple as whether you are comfortable hanging out at your hotel on the cliffs. We tend to want to move around so that wasn't ideal for us.
