I see that there is a fixed charge of $45 + tolls and tip - giving a total of $60 - for a taxi trip from JFK to midtown. And from what I understand, this fixed fare also applies to a journey from midtown to JFK. Can we just hail a yellow cab on the street and assume the fare to JFK will be this fixed fare? And does it cost any more for our hotel to call a yellow cab for us when we are ready to leave? I am a bit wary that they might call a 'private' (or limo) operator which would end up being a lot more expensive. On the other hand, we are four people and will have four suitcases + hand luggage each so we would probably need a minivan cab rather than a standard saloon cab - and I am wondering would we be likely to get a minivan if we just wait on the street?
