Can't give a for Mythos because we haven't been there ................... yet!! But, that's where we're eating our 2nd day there when we go in June! (based on the advice of the DIS which has NEVER steered us wrong!)
can you call from the hotel (RPR) or have the hotel call for you? not that I would (we usually eat 4ish), but just out of curiosity and for anyone else reading this thread that might be interested
Check on Mythos hours while you are there. If the parks close early, Mythos usually closes about 3:00 or so.

This would be my advice as well...for me it would have to be an early lunch to have ROOM for Margaritaville and my day would include the Alchemy somewhere in between! ...but as gschmerl said, Mythos is often only open until 3 and so dinner isn't always an option!
