I spend around 4 weeks a year in Cape May and can verify the accuracy of the RR listings of main frequencies for the Wildwoods. You will pick up most of the action in Wildwood and North Wildwood by monitoring PD dispatches of 154.965 and 155.64 along with Island Wide EMS and FD 155.79. All toneouts are on 154.13. Wildwood Crest PD is on the NJICS as correctly listed in the DB but the FD is still on Island Wide VHF. I can't verify the various tac channels and Morey's Piers in the Wildwoods as I just use handhelds when staying in Cape May, but as the DB does seem to be accurate I would just enter them in your scanner. You should also be aware that Wildwood and North Wildwood PD are fairly low power. Years ago all three PD's dispatch repeaters pegged the signal strength to the right but in recent years the signals are scratchy on handhelds in the section of Cape May closest to the Wildwoods. You will hear things just fine on the WW Island, but if you are a few miles away the signals will be surprisingly weak.
I would also enter the Cape May NJICS talkgroups if you have a capable radio. I have heard some action on the fire channels during Wildwood incidents, and all adjacent towns to the Wildwoods are on the system now, including Stone Harbor, Middle and Lower Townships along with Wildwood Crest.
BTW I am currently in Cape May so my information is current.
