A group can be from a minimum of 10 passengers to an unlimited number of passengers!
You choose the group size.
Free places are usually offered for groups of 20+ but if you require a free place built into a smaller group then just let us know.
If you prefer to travel as an individual or smaller group, this can be easily arranged and tailored to your needs or you can join a private group tour which hasn’t reached maximum numbers.
You will be guided through the booking process and will be updated as plans progress.
