Beware of OTEL travel. Last November, I placed a room reservation with OTEL for my upcoming trip to Prague. The charge was immediately processed on my AMEX as I expected. Last week, I received a e mail from OTEL asking for a duplicate payment on Mastercharge. Their reason was they were having some problems with AMEX. I emailed back that any recent problems with AMEX shouldn't affect my reservation since it had been paid long ago. They said with out a second payment, my reservation would be cancelled. I read this morning, that Frontier airlines filed for bankruptcy because the credit card companies hold back a certain percentage of the prepaid charge until the trip has been taken. They recently uped that percentage which cut off cash from Frontier. It appears the same thing has happened with OTEL and I would expect it may have the same problems. So BEWARE of prepaying for anything on OTEL.
