My friend and I spent 2 nights at Carlton Lodge whilst going to the Southport Music Weekender at Pontins (hence not much sleep had haha!). The owner (think Christine?) was absolutely welcoming and nothing was too much trouble. Rooms were small but comfortable. Very central location for Lord St and the Promenade. We only managed breakfast on one of the mornings, there was plenty of choice on the breakfast menu, I had the full english which was scrumptious. Definitely recommend this B&B in Southport.
