I had a short and straightforward booking for a Virtuoso rate for which I, frankly, didn't want to bother an advisor. So I decided to book online via the ClassicTravel portal. I did not receive a booking confirmation by email. Called a couple of times but the phone wasn't answered. An e-mail also wasn't answered for a few days, after which I decided to cancel and reach out to another TA. Booking was then handled within a day and I had the confirmation in my inbox swiftly. Don't know if this is standard for ClassicTravel, but I wasn't impressed by the absence of customer service availability.
