Not much I can tell coz I'm not really active in using their services. Maybe coz I don't really have time for holidays. But I can see that they have added some more hotels for international vacation from time to time. But for booking they advice to plan early, better plan for one year booking.

on customer service I got mix experience, some time ok other time quite slow. Another advantage I guess is you can lock your budget for hotels... coz the room rate will increase year by year.
