I am probably one of those people who would be irritating on holiday. I get flustered easily, particularly about flights, and tend to end up relying on other people to keep calm and sort things out. I can see that it would be very annoying for a travel companion.
I went on a celebration break with my friend. All the other members of the group were friends of hers or work colleagues. I felt very uncomfortable and was glad to get home. It was nice of her to ask me but I would steer clear of going with a group again because I am not very confident amongst groups of people I don't know, and may well be seen as a bit stand-offish or a wet week.
One of my most treasured holidays was with my husband, daughter and grandson. My daughter and I sometimes had a rather strained relationship but that holiday was just so perfect, to the extent that I was not looking forward to going home (which I usually am).
My mum accompanied my husband and I on several holidays abroad and at home, and it was invariably quite difficult. She tended to get obsessed about buying a particular item of clothing, accessory or bag and we would have to trail round shops looking for them. My husband seethed inwardly and, on reflection, I can see that it was more difficult for him than me.
Another holiday with friends was not a great success. They did not want to put the air conditioning on in the car, to save the expense and they constantly referred to the cheapness of other destinations they had travelled to, compared to the one we were at. We are still friends but are not so close as previously.
I enjoy going on holiday with my husband, and we get on better then than when we are at home. I don't think I would be a good travel companion for anyone else.
