rfranta is simply spouting the same rhetoric that is spouted by the sales people when they are trying to seperate you from your hard earned money. If he/she really believes what they are writing I can only assume they also believe in the tooth fairy.
Paying 3k upfront in the hope of getting cheap accommodation doesn't sound like a good investment to me. I actually went to a similar presentation and challenged them to match a holiday that I had already booked. They had to admit that they couldn't come close to the prices I had obtained for myself simply by using sites already freely available to anybody with internet access.
Bottom line from my viewpoint is :- Don't touch them with a 10 foot pole.
