Wonderful, wonderful, wonderful! They are the only company I've used, and just one time, but I am hard put to think of how any other company could've been better (I'm sure some are just as good, though). What particularly impressed me was the pre-trip contact, done through e-mail and very quick, friendly, and professional. When my reservation confirmation got caught in my spam filter and they hadn't heard back from me, they actually called very politely to check to see if I still wanted the reservation; w/o that call, I wouldn't have known and the reservation would've been lost. This was last March; at that time, only one or two others here had used SE, but since then a number of folks have and I haven't read a single complaint.
