I get up earlier when I am sleeping in a hotel, not matter the location. At home I am usually up by 7am, when away from home by 6am. It is great because it gives me time to exercise and get myself ready before I have to get DDs ready.
Starting on the day I leave, I get up around 3 or 4 am, voluntarilly, no alarm or kid assist needed. I couldnr sleep later than that knowing that we're due to be at Dis or Uni, whichever. Once there, every other morning I am still up before 7. Any non vaca day, I drag myself out of bed around 7, sometimes dd or dh have to get me up at a quarter to 8. Also while away from home, I cant sleep for more than 2 hours without waking up for at least 30 min. drives dh nuts!
Yes! I force myself to sleep while waking up and looking at the clock every 15 minutes. This always happens on the first night! I loved sitting on the balcony at 6am watching the maintenance guys on the golf course. There were also joggers and several animals out that early. Getting up early and staying up late stretches out the vacation. Sleep is for home.
