Have you decided what you're going to do yet, Deborah?
looking at Seashore Resort but cannot work out trouble free route, which long out long troublesome bus routes.Edited: 05 April 2017, 20:22
In that case you want the train to Great Yarmouth. www.nationalrail.co.uk for journey planning. it looks like you can do it with only 2 changes from Glasgow Central going via Manchester Oxford Road and then Norwich to Great Yarmouth. Or it's the east coast route via Edinburgh, Peterborough and Norwich. Either route is a long train journey! It's about 2 miles to the holiday resort so I guess a taxi would be the easiest option from the station.
I can't help thinking there must be caravan sites that would be a lot quicker and easier to go to!
