Up until the end of February, the El Cortez (in downtown) is offering free breakfasts to those who stay for three days concurrently.
Not sure if you understand just how bad food is in Vegas for us brits, so although it sounds good, it wouldnt sway me to stay anywhere.
A good tip is to eat brekkie at the Venetian each morning as its the closest you will get to an English fry-up!
