I would never trust a hotel wake-up call to get me up for anything important, dguruswamy. If that's the first time you've been missed (even at a 4 star hotel), either you don't travel as much as some of us, or you've been very lucky. But I do sympathize. You can try writing Hilton Customer Service about maybe getting a voucher as compensation for your cancellation fee. Good luck.
ClassicalGal, is the "Travel Companion" you mention the same thing this person is asking about in General Travel Talk?
Sharper Image's travel companion?
It sounds interesting, although I really don't want one more thingy to haul around. I have a box full of travel alarms, but now use my mobile phone as an alarm, pocket watch, etc etc. In the US, of course...
We were talking about Lima, Peru, and not the one in Ohio, weren't we?
