Its a long time and i wondered if others out there had some good ideas for activities, particularly inexpensive ones!
I live in Northumberland and would like to recommend Alnmouth beach as you can park really close and pop back to car easily.
Not exactly cheap unless you go regularly then its only £25 a year is the Alnwick Gardens. Bring spare clothes for you and kids as you'll have great fun in the fountains on a warm day.
