Travel can be as easy as you want it to be if you are willing to spend money and/or plan. Stay at hotels that are part of a hotel group (e.g: Marriott) and check-in will be seamless. Use airport transfers and someone will be waiting at the airport with a sign and take you straight to the hotel (any reputable hotel will arrange it for you at a fair price). Use a global e-sim that you can activate when your plane lands. The pain you're describing is a choice (a completely reasonable choice to make for many people, but a choice nonetheless).
