The small things can sometimes make a big difference.
At my favourite lux hotel in Dubai (had more than 50 stays there), I always get escorted straight to my suite and the check-in process consists of me signing a piece of paper - no ID and they never ask for a credit card / a deposit. Being able to skip the whole check-in procedure can make a big difference, especially after a long flight and seeing a queue at the front desk
When I think about it - the best hotels I have stayed at where the one’s where everything felt effortless / care-free, and it just feels good staying there. Even if something goes wrong, you know it will be fixed quickly & in a professional manner, so there is nothing to worry about.
what i hate the most is lux hotels that nickel & dime - and where you literally have the feeling they are just trying to squeeze out every cent out of you or argue over extremely petty things, despite the daily room rate being 4-figures.
