With 4 people in a room I would definitely NOT go with either of the two Mozy alternatives! Westin has a lounge and I have had some pretty spacious rooms there (if your not lucky enough to have the SNA clear). At the LeM there is no lounge and basic rooms can be small. Jr. Suite is a nice suite but just know that it’s not two separate rooms if that’s what you are looking for in a suite. I’ve spent many more nights at the LeM than the Westin but that’s just me.
