Not a pop at you mate. I just can't stand jfk transportation especially and so just cuff it. Conversely I wouldn't dream of getting a cab from Heathrow into London, but then I am never there on holiday and don't find looking at Brentford in traffic fun.
Exactly take the taxi and enjoy yourself. Never see the point of going on holiday and jumping on and off buses to save a couple of quid. That's no holiday, alright if you are 19 or something but no not any more.
