Once you have booked an included tour with multiple times, is there any way to see if any other time slots have opened up? Or might an email to ’tellus’ work? We reserved the 11:45 one because all the earlier slots were taken and that conflicts with an interesting optional excursion. Would it be smarter to cancel the free one and book the paid excursion? Then maybe we could hope to get on an earlier version of that day’s included tour when we get on the ship? I really should have gotten on CC earlier. 😢
