Cruising the British Isles

My wife and I are planning on cruising on Princess Cruise lines (Ruby) in couple of weeks. Just noticed that the ship is using MOTOTRBO, so looks like my 436HP is not going to work for that. Wonder if anyone has any scanning experience with England, Ireland, Scotland, and surrounding areas. I believe that all law enforcement is encrypted. My question is "Is there anything to really scan over there?" or "Should I maybe leave the 436HP at home and just bring a portable shortwave radio?"

Any tips or advice are welcome. Thank you.
