Aircraft
Hi
I think the microlight or vla route is a good one to go I operate GA aircraft for my bussiness but have built and fly a Sportcruiser for my fun flying. You can do a lot more if your not always thinking how much it costs. I think as has been said a group can offer a lot but if you can afford it having your own aircraft has its appeal as well. Why not look at just a group of two. 300 hours per year is a lot for one person you might find you do not do that then the fixed costs start to build up. I have done a little flying in the UAE (Umm Al Quwain) when it was open and am in Dubai again in Feb 2012 if you want to chat over things. The best of luck with whatever you decide.
