It depends where you live and how many of you are going. My sister, 2 friends and I looked at flying from London. It would have cost £600 for four flights, but we booked the Eurotunnel for £120. The stuff that needs to be in the car (extra bulbs, high vis for each passenger etc) has cost about £20, the tolls will be around £40 and we should be able to do the journey on one tank of fuel which will be around £60. £240 or £60 each. Even if there were only two of us it would still work out cheaper than the flights. We are going from central Kent.
With the flights you also have to factor in travel costs to the airport and transfers at the other end to DLP.

Worth looking into for your dates and see what works out best for your needs.
