The team at the Dorchester can arrange a babysitting service – day or night – from a trusted service so that you can enjoy the spa or various bars and restaurants on offer. The room service menu caters to children, but the restaurants are very happy to have little ones at the table too, even The Grill by Tom Booton, where one mini me sat throughout an entire dinner, alternating between eating, colouring and watching shows on an iPad. But the cherry on the cake has to be the ultra-fancy spa at 45 Park Lane, where hotel guests can book in and which offers two child-friendly swimming slots a day.
