I have a 200 honda accord and the maintenance required light has just come on and is staying on also when the car is just sitting idle the temp starts to rise but goes back to normal when I keep the engine revs above 2000 or start to drive again both the a/c fan and radiator fan are working when the a/c is on what could the problem be and will it be costly?

The maintenance required light is just an oil change reminder. To reset it, with the key off hold in the trip reset button on the dash while turning the key on. Continue to hold button down until light flashes and then it's reset. The temperature sounds normal. They always run hotter at idle because the fan is programmed to come on at a higher temp than the thermostat. Make sure it is still full of coolant though.

OK, you need to get it to a shop ASAP and have it pressure tested to find the leak and repair it. The manufacturer recommends only using Honda coolant but there are some excellent universal coolants available. It's not real important now because they are likely going to have to drain it and refill to repair whatever is leaking.

If getting it repaired is not an option until Friday could I just keep topping it up until then?

I wouldn't take that chance. You have no idea what is leaking or whether it could suddenly get much worse. It only takes seconds of too much heat to destroy the engine. I would park it until it's repaired.
