Have a look at what I said in the second paragraph : For me, the sentence which expresses enjoyment is the version with like + Ving

As for your other question - in real life communication it's impossible to have a sentence which doesn't have a context. Language is always used between at least two people (speaker/listener(s); writer/reader(s)) and the context is established by that : Where are they? What's the speaker/writer's purpose? What's their relationship? What's the surrounding co-text etc etc

Here, the distinction between whether the infinitive form expressed enjoyment or a recommendation would probably depend on the co-text, as in my previous example I don't like going to the dentist, but I like to go every six months so that there's never any huge problems.
Here the co-text makes it clear that the infinitive can't be talking about enjoyment. I've already said I don't like (=enjoy) going, and go on to give the reason why it's a good idea. The interpretation of the infinitive is therefore clear.

If on the other hand someone said :
A : My favourite sport is skiing. What about you? Do you like it?
B: Yes, I quite like to ski though it's not my favourite sport by any means.
A's first utterance makes it clear that the conversation is about enjoyment - and so B's reply would probably be interpreted in that sense.

But if you just invent a sentence using like to+ infinitive without a context, there's no way of deciding.

Hi susan,

Your above example made me think of a question as follows:

I don't know if the listener B skis or not, but I want to find out if he/she enjoys it. Is it OK to ask him/her a question like this below:

A: My favorite sport is skiing. What about you? Do you like to ski, too?/ Do you like skiing, too?
B: I don't know. I have never done it. But I would like to try if I have a chance.

Many thanks.

As I have said above, as a British English speaker I would always say Do you like skiing? in this situation. But I know that in US English (which is rapidly influencing UK English too) the to + infinitivestructure is also used, so I imagine it would be fine - which is why it's included in my example. Look at B's reply : Yes, I quite like to ski . Obviously, if it can be used in an answer it could also be used in the original question.
But notice that the concept of enjoyment has already been established by the co-text : My favorite sport is skiing. What about you? This is the important thing that allows the listener to understand what s/he is being asked about.
