I would go ahead and book. My advice to first timers is to book their dream destination so that you can calm those pre-departure nerves by thinking 'if it all goes horribly wrong, atleast I get to see a place I've always wanted to visit.' I did this trip a couple of years ago and although the itinerary has changed a bit, you will be guaranteed an amazing trip. This remains one of my favourite destinations (out of 20 holidays) and one I will definitely repeat in the future. The scenery, wildlife, accommodation, food and drink are all superb. Add this to a group of people who share your love of travel and enjoy a laugh and you've got a winning combination. Ask yourself, what have you got to lose? Be careful though, these holidays are seriously addictive and once sampled are impossible to resist.
