A2 Economics leisure market investigation - package holidays

Over the summer I have to complete a leisure market investigation on packet holidays. It's supposed to be "an investigative report based on the practical workings of the industry supported by up-to-date data", including stuff like pricing in the industry, takeovers, economies of scale, how productively efficient firms are etc...
I haven't a clue where to start or how I'm going to find out most of the information, especially those last 2 points. So I was wondering if anyone has any ideas/has done this before and can help? Thanks
