Quick picks
Choosing a pool hotel in London
Most hotels in London just say "swimming pool". The detail that decides a family stay is when children are allowed in: many hotel leisure clubs only let under-16s swim at set times, often a couple of hours in the morning and late afternoon. We pulled those times from each hotel's leisure pages, timetables and listings.

Tips for a hotel pool stay
Check the children's times
Many hotel pools only let under-16s swim for a few hours a day. Plan check-in and breakfast around them.
Ask if the pool is included
Most hotels include the pool for guests, but some charge for leisure club access or sell it as a package.
Bring swim nappies
Almost every UK hotel pool asks for them for babies and toddlers, and armbands are usually fine.
Spa pools are often cooler
Leisure club pools used for lane swimming can feel chilly to small children. Ask if warmth matters.
Book a family room early
Hotels have few rooms that sleep four, and they go first in school holidays.
