Police officers at Tenby, Saundersfoot and Narberth attended 130 calls for assistance over the Easter Bank Holiday weekend.
This represented a reduction of 40 calls over last year's Easter holiday break.
Inspector Les Clark at Tenby police station said: "Although the area has been very busy, the Easter period has been relatively peaceful.
"Officers have had to deal with some isolated incidents of violence and disorder, including one that involved officers tackling a very violent person who was armed with a weapon. He was persuaded to surrender himself peacefully and arrested.
"Officers have been very proactive and detained people for carrying offensive weapons, criminal damage after trashing a hotel room, possession of controlled drugs with intent to supply others (trafficking) and two drivers who provided positive breathalyser tests."
Another incident involved three naked young men who thought it would be a good idea to go 'skinny dipping' at Tenby's North Beach late on Saturday night.
"Unfortunately, they decided to undress in the railway station car park and walk to the beach... right past the police station," said Insp. Clark.
Parking has also been a challenge for officers.
"Several calls were received at the station complaining about abuse of residents parking bays," he stated.
