My experience with GCT and the Program Diectors differs from the post above.
Yes, you have the same group the entire trip.
But,
- local guides are used for most, if not all, group tours. The PD is on the tour, often as a “herder” bringing up the rear.
-All PDs are available to you for advice on DIY activities during free time.
- on most cruises, one or more PDs will organize a group activity during a day’s free time.
The slowest person in the group rules, like just about every group tour I’ve ever been on. My experience has been that the PD is usually proactive in dealing with a significant outlier, even to the point of suggesting that they don’t participate in certain activities.
