The SS site has a nasty little IT trick that can hurt. I'm sure they meant well by making it impossible to book overlapping events, but ...
Book an excursion.
Go back later and attempt to book the same excursion, but at a slightly later time, and that shows as Available, NOT Waitlisted.
Web site says cannot book the excursion at the later time because of conflict (overlap) between times for the two.
Must therefore cancel first booking in order to make later booking.
Immediately (and I mean within seconds) attempt to book the excursion at the later time.
Web site now informs that the second booking is in fact NOT Available, but is Waitlisted.
Now have no confirmed reservations for either time for that tour, and both are now shown as waitlisted.
Annoyed. If the later schedule had shown as Waitlisted, I would have never touched my original reservation.
Based upon what I've read, I assume, unlike other RCL lines, that SS allows no communication with the Shorex desk for customers using TAs for reservations?
