Back in the "old days" before pre-booking, when they first "opened" the tour desk, it was a riot scene...I mean we all waited on lkine for fear of sell-outs...
Now, just the convenience of not having to deal with it once on the ship is worth the pre-booking in my mind...
Las three cruises, we have pre-booked by internet...
Only drawback to Celebrity's pre-booking, compared to some other lines, is that they charge your account\ upon booking where some others charge only on sailing...
But, among the things we learned is that you can always change or cancel once on board (as long as it's not immediately before the tour)...
So, my advice is to book ahead...It also allows you a choice of times for some excursions...and those times may fill up as well...
The great part is that it's one more concern you needn't worry about once onboard...
