Please forgive my ignorance.
We have rarely been abroad and when we have have always booked a package 
This year we're going to be brave and book an activity holiday which is the holiday only. We will need to book our own flights and want to spend a few days in the airport city too.
So, how do I go about it? I have visions of booking the holiday and the hotel but not being able to get flights, or the price of the flights increasing markedly after I've booked the holiday, or booking the flights and then not being able to get a hotel or the activity being being fully booked.
What order am I supposed to do it in?
