9/5-9/9 four nights; rental car; visiting as many attractions as possible; safe bus or train OK as needed; seeking $55 & under bid deep discounted 3*, 3.5*, multi-property-stay OK; flying in & out STL; a. parking city center seems to be typically $44/day no in-out-in, or $65/day valet in-out-in; are there low end hotels with big parking lots that offer cheaper rates to non-guests? (in otherwords, stay at 3*+ but park cheap at nearby 1*) (came across that in Atlanta, a Days Inn downtown offered $7/day no in-out-in) b. what zones should be avoided due to crime, shooting, unsafe outside hotel in evening, etc.? c. what closest-in city center zones start to typically include free parking or, say, under $10/day in-out-in? Read in another thread about North Nghbrhd zones, are they "the ticket"? Any advice from Chicago veterans appreciated!!
