Yes, it will always be difficult explaining something that is both bollocks on a round earth and bollocks on a flat one.
Lets say at the beach his eye level was 6 ft. A storey in a hotel is about 12.6ft (its a standard) and we'll imagine he's 10 floors up ... its a big hotel. 130 odd ft up for his second viewing.
At 6ft up on a round earth you can see 3 miles.
At 130ft you can see 14 miles.
CalculatorNow a round earth is supposed to be about 25,000 miles in circumference.
Monterey is -33.9751785 North of the equator. So at that point the earth has a circumference of 19,000 miles. And despite the sun covering 19,000 miles of land in 24 hours it will cover 19,000/24/60 13 miles a minute. And he can only see 14-3=11 miles further.
So if he takes just 40 seconds to run up the beach, into the hotel and ascend 10 stories he may just see the last slither again, but its unlikely.
He certainly did not enjoy a sunset again.
A sunset usually takes about 20 mins at that latitude. To see his sunset again, he needs to see a further 19,000/24/3 (20 mins) = 263 miles.
Ergo he needs to climb 45,000ft or 3571 storeys in under a minute. A quick google search tells me there aren't any hotels that tall in Monterey.
The moral of the story is that round earthers will often imagine a phenomenon in their head and assume that's what happens and say they did it. How many pilots do we have that have been in a mig25 up to 60,000ft?
You are under no obligation to answer these types of questions because the OP is disingenuous. They are pretending to be zetetic but they are actually just bad at being philosophic. Tell them to f-off.
