London Eye

A nautical ship to climb, a double slide and talking tubes, all fenced, and it suits toddlers up to about 11.

Family rooms with pull-out beds, and the river walk starts at the door with the London Eye just along it.

South Bank hotel with sofa-bed studios for 2 adults and 2 kids, some with a kitchenette, and a heated indoor pool.

Fresh pasta in a small Covent Garden room with no highchairs, suited to kids old enough for an ordinary chair.

Aldwych hotel with an 18m indoor pool cleaned with minerals, baby bath, bottle warmer and steriliser, and cots and extra beds.

A playzone of little trains, boats and a cable car your kid gets to drive, made for under-fives.
