How do I know if I am getting a good deal!?

[Ah80207]

I was going to book to visit DLP for 3 days in March as it seems it gets a lot more expensive after April. There was an offer for free half board saving us around £400, which seemed a really good deal and I nearly booked. It would have been £1500 for DLH, 3 nights, 2 adults and 2 kids including half board. But when this offer expired, they introduced another offer, and this brought the cost down to £1000 without half board, so better value as half board is under £400. It got me thinking, I have been to Orlando many times but not got a clue how to work out what is a good offer and what isn't in DLP. Any tips? Does £1000 for 3 nights (including breakfast and park tickets) in DLH in March sound like a good deal? Thanks in advance
