It's really weird how hotels scale up. They prioritize appearance of luxury over function in most cases.
Will I be able to be able to stream video to the TV? Probably only at cheaper hotels. Beds and rooms get bigger, fine, but showers and closets? Could be tiny. Gyms? Some great ones out there, but it's really inconsistent, a lot of expensive places still just have a row of treadmills, some dumbbells, and giant inflatable ball.
Extreme breakfast buffets are a common perk. Would you prefer to pay $100 for the same admittedly phenomenal breakfast several days in a row, or would you rather spend that money and those calories on the best dinners in the area at several different places?
Towels. Towels are the only thing that's predictably better. Something's strange about paying a few hundred per night on great towels.
There's an opportunity for a mobile concierge service. Uber eats, sure, but maybe also press clothes for less than $50 per item. Maybe it could even loan you a set of really great towels.
Try staying at a five star resort villa style hotel in Bali or some other SE country. The last one we stayed at was two stories with a living room/kitchen/massage room on floor one (next to a private pool) and the bedroom/huge bathroom/walk-in closet on floor two. Seriously would love to have a real house like that. Most of the bungalows I’ve stayed in haven’t been as elaborate but have felt very much like home.
Hotel rooms in the city are always much smaller, but non urban tourist areas are very different (Eg Manila vs Boracay).
Your description sounds a bit like a luxury version of a nursing home.
