servicio a la puerta de taxis

"porter" is ok IMO ... they're there for you and take your bags up to your room (don't forget the tip)

based on what has gone before, I think "porter" would be ok

Whether it's true I have no idea; quite possibly not. Perhaps Mexican hotels haven't always done this, and we don't know how long ago this hotel started doing it. In any case, as Joshua says, the truth of the statement is not a matter for us; we are only concerned with its meaning.

I must admit that when I saw the phrase, before I read the question, I assumed it meant a taxi service to the door, but it struck me as very odd to express that as "servicio a la puerta de taxis" rather than "servicio de taxis a la puerta". The order does fit the meaning Joshua's client has explained: the door is that of the taxi, not that of the hotel.

You say it's not for you to question, but I would feel justified in adding a polite note saying that it sounds odd and suggesting that they omit it. They can't prove that they were the first - I can't imagine any good hotel, even centuries ago, not providing this service.

The sentence definitely means what I originally stated: the hotel helps guests right to and from the door of their taxi (with their bags, etc). This was confirmed by the client.
I'm not sure I could give the name of the hotel, but that's definitely what they're claiming: that they were the first to provide this service. I don't know whether that's actually true, but I don't think that's for me to question.
With that in mind, I think some of the options offered here may be unsuitable: it has nothing to do with a taxi rank, or the taxi ride itself, or anything else. As Charles said, "taxi door-to-door service" is idiomatic but I'm not sure that gives the right idea.
I had "taxi door-service" but didn't like it very much and asked the client to confirm the meaning, so I'm looking for something better. I think I may have no choice but to expand/explain it as Charles suggested.

How do you know that your explanation is correct - is there something else in the text that says this, or is it just an educated guess?
I don't suppose you'd be willing to tell us the name of the hotel? That might help, and you're not giving anything away unless you're working directly for the hotel.
One possibility is that the Spanish is not very well written, and would be unclear even to a native speaker. Also, it could be untrue - how do they know that they were the first to provide this service?
Could you query it with the customer?
