We stayed at this property last May on an standard room award stay. (I don't remember how far out I booked it but some where in the 9-10 month vicinity is what I recall.) The rooms are nice size and the staff was very friendly and helpful. We didn't eat at the restaruant at the hotel. There are nice options for that on the island. Here are a few links of TR's of the JW Marriott Capri.
