Definitely can't afford that, this is going to be one of those life regrets I think that I won't be able to do.
Worth noting, though, being able to "afford" this kind of thing isn't just about the money. Most people get only a few weeks holiday per year, and many aren't allowed to take more than a couple of at a time. To get the most out of something like this you'll ideally have a month at the very least to holiday, which is not possible for most.
