Hi Jonah,
Don't worry, that's alright!
I can tell you that there are 25 travellers on this trip. 5 are male and 20 are female. The age ranges from early 30s - early 80s. The Tour Manager will be Linda Robinson.
In terms of your luggage, yes you will need to bring your own luggage with you but you will receive assistance with this upon your arrival.
There is no luggage restriction on the train, but British Airways does have a 23 kgs restriction for each bag you take.
I hope this helps!
Kindest Regards,
Amy
