We still use the T5 on its own for the odd one/two nighter for just us. Occasionally a child (they are now all adult) meets up with us when with the Eriba, as our daughter did last summer for 3 weeks in Italy and our elder son for a week in Switzerland, so it means they have their accommodation and we have ours with a bit of space inbetween.... and we could also do a partner too and still had a double bed to spare.....I guess we'll ultimately get grandchildren, although I don't like to presume!!
Each to their own of course but I think our T5 will be with us for a while to come.
