Just thought I'd post a bad experience we just had using "Barco Tour Operator" (that's what's on our receipt) in Antigua 2 weeks ago. We paid for the tour to Pacaya Volcano, and arranged our entire day around being picked up at our hotel at 2pm. They never came. The clerk at our hotel kindly called them and was told they forgot to put us on the van driver's list. They tried to talk us into going the following day but we couldn't, and weren't inclined to give them a second chance they might screw up. We told them we'd be right down to the office to get our refund. When we got there no one but a cleaning person was in the office, even though they were expecting us. After much hassle we got our refund. We think they overbooked and didn't want to admit it. Leaving the office when we were on our way for a refund was nasty. Also it appeared the cleaning person jerked us around pretending not to speak any English (but when it mattered she suddenly was capable). Overall the experience ruined our brief time in Antigua.
