is there much space in the rooms provided do you have to share ?

Hey! The provided accommodations depend and vary from destination to destination. Somewhere you might stay at the hotel, somewhere get an apartment, but what you have to know is that you will get your own room, so you don’t share your room with someone else. And again, the sizes of the room vary from place to place, there is no standard for the size of the room.
Anyway you will not spend a lot of time in your room as in each destination there are so many things to see, that during your time off you will be exploring!
