NOT COD and SWEDES, Don't knock the benefits of public transport! We have friends 250 miles away, and take turns several times a year visiting each other for the weekend.
When they come to us, they often arrive tired + a bit stressed after battling with heavy traffic down the M25 of a Friday evening. When we go to them however, we take the train, arrive relaxed after a pleasant 3 hours spent travelling in seats we've pre-booked, with a table so the dc's can spread their toys out, we all make use of the nice buffet service + arrive having had a stress free journey!
Recently they decided to take a leaf out of our book, + the last couple of times have travelled to us + back by train. They were surprised how stress free their journey was (also with 2 young dc's!), and do this every time now.
Our in-laws recently offered to pick us up to spend a weekend with them, (an hour away + we normally take the train). Our dc's were disappointed at the thought of missing out on a train journey so we made our own way in the end, to be honest, a lot easier!!
