Any overnight garage parking options near Hilton West Palm on Okeechobee

Hi - need to stay at the Hilton on Okeechobee and will have my car with me. Just learned that they only have valet parking - no self park and it's $55/day. Are there any garages nearby where I could park my car and walk over and then grab my car 1-2x to come and go (I realize you pay again if you go in and out but it could still come out to less than $55/day). Obviously looking for safe options - i.e. car will be safe there overnight on Sunday/weekdays when it gets quiet + I'll be safe as a woman traveling alone going to and from my car. Any such options or just deal w the $55/day and having valets in my car every time I want to use it?
