Just to pile on complaints about HRN
I've twice booked hotels through Travelocity's "value rates" and both times arrived to the hotel only to find out that they've never heard of me (even though I have the printout of the reservation in hand).
Both times it turned out to be booked the HRN. Luckily having the printout helped a lot and the hotels were able to figure it out.
I still book regular rooms through Travelocity but refuse to use any of the "special value" rates.
