Answer

There are a few similar phrases in English. Some examples are:

‘Don’t give them false hope, no one knows how this will turn out’
‘I don’t want to get my expectations up about the trip’
‘You shouldn’t lead him on’
‘I was kidding myself that I would just turn up and get the job just like that’

Answer

Ilusión can be translated to ilusion but in this context it is hope (esperanza).

I don't want to give them false hopes. I don't want to have false hopes about the trip to Cuba. You shouldn't give him false hopes.

And you don't make (hacer) and give (dar) hopes in English but have (tener) and give (dar).
