Hotel recomondations for monster mopar

Looking for recomondations for hotels for monster mopar. Would also like to go to the arch and some other stuff in st louis. Will I be better off staying in collinsville and then driving to st louis to do the stuff there or better off staying in st louis by the arch? I see that doubletree in collinsville is the hotel on monster mopar site. Have never been there so looking for suggestions.
