Have you tried YouTube? Maybe there are some videos there that will give you the kind of feeling you are seeking.
The above is a general one. But I think I'd also dig deeper there and try things like "Pullmantur partying" or "pullmantur english excursions" or ??
There is an amazing amount of info there. I've even watched tricky knitting stitches until I got it. Once I was wanting to walk from my hotel to a cruise ship port, and found a video somebody had taken of them doing exactly that.
Does Pullmantur offer any of their excursions in English?
