AMS-LHR,
In answer to your question, it entirely depends wheich country you are flying from. From the UK, you have the same restrictions as pax. So check with the airport manager of the airport you're flying from. But, to be honest, if you are checking in a bag for a night stop, may as well check it in both ways, less hassle that way.
I always take my laptop away with me, but don't make the same stupid mistake that I did and leave it on board, someone will have it in a flash!!!
Good luck on your course, my sis starts on the 16th.
