I was on yesterday's CO Flight 61 BRU-EWR which was cancelled due to mechanical issues. I was rebooked today on flight 1951. Am I entitled to compensation under EU's rules for cancelled flights?

Also, I did not end up getting a hotel voucher from CO because they only had one person handling 200+ people, and I didn't feel like waiting after sitting on the tarmac for 4+ hours. Any chance of getting CO to pick up the hotel bill?
