Hi Haggers .... we have various opinions about this company cropping up in several of our forums. You should be able to retrieve them all by using the Search facility at the top of the page.

However, one thing which you should bear in mind is that A2B is not a transfer operator as such. The company acts as a booking agent or broker for numerous transfer operators and in acting as a middleman in the booking process, A2B would pass your reservation on to be serviced by another company.

Our members may be able to give you an idea of their experiences of that booking process, but it may be more difficult to comment on the service and reliability of the actual transfer, as that may be operated by any one of a number of transfer companies.
