Thanks will.
My tastes in travel lead me to venture to areas where hotels don't provide alarm clocks (or hot water, or sometimes, any water at all....) or wakeup calls (i wouldn't necessarily be able to communicate with the staff anyway. I can just about check in with a passport and USD). These types of areas are also susceptible to power cuts, which I why I don't rely on chargeable devices. I might really take 2 alarm clocks with me next time.

Yeah, part of the reason I struggle to wake up is I can't sleep the night before stress in about missing my early morning ride!
