I was in Budapest last week and had pre-booked a sightseeing tour w/TGV and airport transfer (outbound). They were supposed to pick me up at the hotel at 1330 for the tour and never showed. While I was walking toward the Danube I saw their offices and went in to inquire...where I was told that they cancelled the afternoon tours because of a parade. I then tried to confirm and pay for my airport transport but was told the phone number was busy. They told me not to worry, my booking had been made and I could simply stop in the next day to pay. Well, when I stopped in to pay (about 6 hours before my flight) they told me that they couldn't find my reservation (even after I produced the E-mail traffic between me and their company) and that there was simply nothing they could do since the service was now fully booked. I was forced to take a cab to the airport...~4000Huf more than the shuttle would have been. I suggest you book directly w/Airport Minibus for transport and find another tour company for sightseeing. I ended up touring Budapest w/just my guidebook and did fine.
