Hi sorcerermickeyuk, welcome to the DIS Boards.
If you are travelling during the school holidays unfortunately you won't be able to find very cheap deals because operators (especially airlines) increase their prices significantly. The only advice I can offer is to compare the cost of package deals with booking your holiday independently (flights, accommodation, car hire, car hire insurance, tickets, etc). We have to travel during school holidays and have found we get better value for money by booking DIY holidays rather than complete packages.
I'm sure you'll get lots of advice on money saving tips here, so keep reading and asking questions.
Regards
Rob
