We sailed Mariner in Med & TA in Aug/Sept ‘23. We booked a handful of months ahead and were shut out of 95% of desired tours. We waitlisted when applicable; not all are. No waitlist cleared and seemingly, no additional capacity was added…so our 95% quite went the other way. I don’t know whether this was bad luck or a reflection of changes in R. I like papaflamingo’s suggestion and will try it for our next booking. We are not willing to bolt out of bed early am, dress, breakfast, etc and then go to the theater to wait IF.
