Joe, why fixated on Santorini?? Is that because your mother-in-law asked for it?? Or because googling "Villa for 9" produced only that Isle? Otherwise, there are MANY other islands where she could be comfortable right on the beach, with level pathways to/from nearby cafes, shops etc, and all of you could enjoy many activities. And on 3 of those good "family" islands (Naxos, Paros, Antiparos) there are excursion boats enabling those interested to make an all-day visit to Santorini. If specifcally looking for a VILLA, it may be difficult to find one with a location that suits a family (i.e., near a beach, walkable to activities). That's because large villas came late to Greek isles; Greek tourism first started for a budget crowd, so beachfronts filled up with small pensions, family-run lodgings. By the time the more pricey crowd came looking for villas, seaside space was gone, so most large places are inland, requiring car transport for all. Also, 9 people using 1 kitchen, 1 LR, maybe 2 baths can be cram-jam, and Mom wants some privacy from kiddies at night. So I suggest looking at beach places in Naxos & Antiparos that have 1-br units w. kitchenettes & balconies on water ... u can have them side-by-side for togetherness when you want, for meals & socializing, and a bit of quiet for siestas or early bedtimes. If this is of interest, post a reply and I & others can supply a long list of useful places to check -- AND u will find probably that 3 such units would be less than an inland villa and the need to rent 2 cars!
