Just logged on to the website of a well known campsite holiday provider to book a holiday in june for the family. The KEY when booking this CAMPsite holiday is to pretend your are dutch or british but definitely not irish. There is a significant difference in price betwen the irish (900 euro) british (650 euro) and dutch (550 euro) for the package we wanted.we phoned them up,i think the office is in cork, and they accepted the discrepency and accepted the lowest price for the booking, 550 euro.So a nice saving there.Some of you might find this useful.
