Tips/tricks for traveling?

Hi all!

I (27F) will be going to Europe for the first time at the end of August for 3 weeks, mostly traveling around Italy but also visiting Marseille and ending my trip in London. I will be mainly staying in hostels, where the beds are mostly bunk beds. I currently use a ResMed AirSense 11. I plan on one bagging my trip along with my CPAP bag. I did look into getting the AirMini, but I definitely cannot afford it.

Just wanted to see if anyone has done this before and if there are any tips/tricks to using your CPAP in hostels and while backpacking. Thanks in advance!
