Why would I spend the time and money on a vacation just to waste it on being lazy? I can do that at home. On vacation I'm up before sunrise, take a shower, and grab breakfast before I start my itinerary for the day.
You can also maximize your time sleeping in too. Stay out and have fun on the town, head back to the hotel at 3am. Some people are night owls, some people like mornings. Nothing wrong with either.
Personally waking up before sunrise feels awful for my body and brain function, but I get it.
We have different vacation philosophies. Mornings are nebulous unplanned times for everyone to do what they want like sleeping in, relaxing by the pool, getting brunch at a nice place, and light sight seeing. I usually don't have scheduled goals/events for the day until afternoons and evenings while on vacation. I can't enjoy being somewhere new if I'm too burnt out and exhausted to participate and experience it properly.
