A very interesting experience for us. We, indeed, booked late. Just tried to book P7 and S reservations. P7 is fully booked for all ten nights. And very limited options in S. We have no doubt we'll dine once in both alternatives. Several of the excursions we wanted are also not available. Not just wait listed but listed "closed." I'm not posting this to complain. We're just pleased to be on this cruise and will be delighted by whatever comes our way. But it is instructive to see how far in advance everything books up.
