My vacation was excellent. Hotels: Art Hotel: excellent value, great boutique hotel Estancia: despite the cold, it was very hospitable. Great food, very comfortable rooms. Good activities Tryp Hotel: Modern, business hotel but good location, comfortable and great staff. Falls Galli: Not a good hotel. The quality was low, especially the rooms. It was clean, but the rooms were sub-par. The staff were not very helpful and didn`t have the best attitude Windsor Palace: Great location, very good staff. Very small room, but clean and comfortable. Food (breakfasts) at all hotels were good. Transfer: Tour Operator in Argentina: Very helpful, friendly, accomodating, on time Tour Operator in Uruguay: friendly, punctual, but fell short. They could have been more helpful at the airport when we got stuck because of the ash. Our guide got us some help, then left very quickly. We don`t think this was the fault of her, but she was underpaid and obviously under a lot of pressure from her boss. Tour Operator In Iguassu: Great! Our driver was very friendly and helpful. He helped us a lot in the airport when we got stuck again because of the ash. We sent an email directly to this company because of how good the service was. Tour Operator In Rio: Despite not speaking much English, the driver was very friendly and did his best to communicate with us. But the tour guide (whose number we were given upon arrival) was not very responsive to our questions and bookings. It took him a long time to return our emails/calls. Flights: The flights from Montevideo to the Falls would have been fine had there not been the problem with the ash, but because there was, we ran into lots of trouble. (Because each airline would tell us to talk to the other - Pluna and Tam). Because of this, we don`t recommend having flights booked through two airlines. However, when we got stuck in the Falls TAM did get us re-booked quickly and paid for our hotel. (We did not get this the first time we were bumped because of the ash) Also, we recommend that people do not fly from BA to Montevideo (or vice versa). They should take the ferry. We spent far too much time in the airport in BA to make it worth it (plus our 35 minute flight was delayed by 45 minutes). It would have been worth the extra money to do the ferry or hydrofoil. Brenda, the agency rep was helpful, friendly and patient with all my questions. She is looking into some reimbursements from the company for our hotel mix-ups due to our flight changes because of the volcano. The website was fine. I was able to find what I wanted.
