I always stay at nice hotels whether mongering or otherwise. Was more just curious what perks/cons I've been experiencing but would be unaware of.
I considered Grand Centre Point and JW Marriot but avoided Grand for similar reasons to you, but I also thought JW rooms looked very dated and bland. Kinda like your typical 5 star American chain hotel that has worse rooms than boutique hotels for half the price.
I have a bad habit of taking girls to fancy restaurants. Mainly because I find it hard to justify expensive restaurants if I'm going alone, but somehow I find it ok if I have company. I don't do it to impress the girls though.
I've never seen the 10 commandments before. Some good tips in there. I'm definitely too honest with girls.
