I've often used booking.com for accommodations as I travel, and for more reasons than that TravelGumbo benefits when travelers make reservations using the link on our pages—but I have another reason now.
When we arrived in Palermo, Sicily a couple of weeks ago, our airport bus+taxi combo made us a bit later than we had told the hosts of our B&B. So, while we were in the taxi, we got a phone call from a booking.com rep, who told us that the host had called, concerned that we might be lost; booking.com then called us and asked if we needed help finding the place.
As it happened, the taxi had just pulled up at that moment, but it was nice to know we had a support network!
