Question for UK people:
 

We are looking at doing a 5 or 6 day train trip that includes accommodations and other amenities. It says $599 per sharing.

What does "per sharing" mean? Would that be per couple in our case?

Sounds like $599 each, based on you both sharing a room. Thats how it reads to me.

I didn't think you were coming here this trip.

"per sharing" makes little sense to me.

Send me a link to the booking/site on FB or something and I'll look into it for ya.

I think it means a room is shared between more than 1 person.
You should talk to the person who made the advertisement to ask what the advertisement really means.

I went to site and read it myself (instead of relying on another), I think you are correct.

I guess Northern Ireland is considered part of the UK . . . at least for the purposes of discussion.

Usually $599 sharing means per person ( ie a couple) ... I have seen it many times.
