I am assuming for the daily "room check". They didn't mention in their post if Housekeeping had been, or if their schedule on marathon day meant they had their sign up more than they normally would have. This is one of my big concerns for my trip later this month. I sleep late, often until 10-11am, and if I am awakened early, I won't be able to get back to sleep and I'll be in a foul mood from sleep deprivation. I don't want to have to set an alarm and get up early on vacation - that's what work is for! This will be the first of four 11 day scheduled trips for 2018, and if it all goes south from lack of sleep, the other three will be cancelled. I am tempted to wear earplugs (although I am allergic, so that brings up a whole different set of issues) just so I can't hear them knock if they do. Let them use their tool, come in and look around, and leave while I'm sleeping.
