We were introduced to this area by our coach driver and it was so interesting we decided to go back on our own when we left the tour.
Easily reachable from town, this starts with a stretch of nice B&Bs, hotels, shops and restaurants then develops into a fantastic boulevard of 'holiday cottages' of the rich and famous. Many of these are open to the public for a fee and you can get multibuy deals. We visited two - The Breakers and Rosecliff and that was probably enough for us. Breakers is huge with magnificent masonry, ceilings and ornamental woodcarvings, whilst Rosecliff ismore intimate and homely. Very well run with good audio guides so you can go at you own pace. Good gift shops. Probably worth 60-90mins each as a minimum.
Weather wasn't great when we were there but we did a little of the cliff walk which would be great with better weather, seeing the backs of all these beautiful mansions. Parking can be a little tricky but is available at all the open houses.
We also tried the International Hall of Tennis and adjoining La Forge Restaurant, both of which we can recommend.
