Hi Sylvia,
The system we check is showing 2018 departures as Grand Hotel Tamerici & Principe and I've just spoken with the holiday creator who has also advised that it is the Grand Hotel.
I've just done a headline check of the itinerary and I can see that apart from the hotel (and therefore in free time, where you will be based) the other difference is where you will enjoy the wine tasting (this has moved from Castello di Bolgheri to Cantina Torre a Cona). The website is currently showing the 2017 itinerary.
In terms of numbers - yes, there are seven travellers currently booked on this date.
Kindest regards,
Julia
