The frequencies alone are fine if you only intend to listen in with a scanner. However, if you want to bring a two way radio to communicate with the other radio users, you will need the "PL" tones that they use also. Otherwise their radios won't "hear" yours. On this subject, do they allow and/or, encourage those of us who have programmable commercial radios to bring them if we volunteer?
