As far as level is concerned I'd suggest it would suit lower intermediate - CEFR B1 - level.

At this level they will already have met the structures and some of the vocabulary - important because you can't include too much new material in one lesson. You r objectives will therefore be :
- to reactivate and consolidate the Ls' knowledge of I want to / I'd like to + infinitive to express wants
- to reactivate and extend their knowledge of vocabulary in the fields of holidays, holiday activities and holiday accommodation.

You then need to consider :
- who are the learners? Obviously the age group will make a big difference to the type of lesson you can plan, but given the topic I imagine they are adults or older teens. But what is their first language? This will affect the type of problems they'll have with the structures and vocabulary - and these problems need to be anticipated so that you know in advance how you're going to deal with them.
- what lesson format is most suitable. As this is mostly reactivation and extension I'd suggest a Test- Teach - Test format. Google it if it's not familiar, but basically a typical TTT lesson might involve
a) asking the learners to discuss the topic in pairs and monitoring them while they do to see how well they are coping with the target language.
b) Focusing on the target language and the problems they've had with it, explaining it and then giving practice activities (remember to deal with one thing at a time - explain it, practice it and then go on to the next) .
c) Getting them to change partners and repeat the initial discussion. Again monitor and follow up on problems, but also note and emphasise how much they've improved.
That should easily take up 50-60 mins given the objectives you've set

Hope that helps and sorry I didn't answer before. For some reason the post has only just shown up for me.
