As SBB train leader for our group of 10 (5 couples) all with Half-Fare card, I've seen Super Saver fares for some of the exact trips we need to take together that are significantly less than using the 30% group booking discount.
My concern is that there may not be enough seats at the Super Saver rate for all of us. I know that we'd have to book in 2 batches, e.g. 4 and 6 people, since only 9 can be booked at once. What are our chances that all of us could get the Super Saver rate
