I'm going to try to take dd in the next couple of days. I know there's a sort of Santa walkabout at Hamley's but I'd really love to take her to a proper Grotto. Harrod's is meant to be good - has anyone tried it? I've heard they have long waiting times and as dd's only 3 I'm not sure she'd handle that ... I'm in SE London so Knightsbridge is also a bit of a pain to get to.
TIA
