- Very convenient parking for the Oklahoma City National Memorial and Museum. It is literally right across the street. This lot does not allow RVs and only accepts credit cards so if you have an RV or want to pay cash you have to park a little further away at the corner of NW 5th and Hudson (405 NW 5th St.). This lot is clean, open and easy to get in and out. It is well marked with a big blue "Public Parking" sign and rates are $2 per hour or $12 for 24 hours. There is an electronic pay station where you enter the space you park in and the amount of time you want and then swipe your card. The machine will ask you if you want a receipt. It is also well lighted at night.
