I travelled with Imtrav last year and visited Egypt. This year I might do the Cyclades. Is it cheaper to book it online or more recommended to go to a travel agent? What I also would like to find out is whether temperatures are still good in the beginning of September (September, 4 eg)? What do you mean by no extra charges if you travel alone? A room for one person is always more expensive, isn't it? How many people already booked "Islands of adventure" for the period I mentioned?
