Went to Cribbs Causeway today with the 3 year old
It was QUIET as anything - no queues
They had a great Santa Castle and a very nice Santa grotto inside (£4 includes soft toy from Santa), and took a nice digital picture (£4 again or £6 for two, but it was so lovely I bought 4 ).
AND brilliant brilliant ice-skating for the small children - strap-on skates with two blades, and slow-moving penguin supports for the children to use to move around the ice. My 3 year old managed it fine.
It was a great day out, could have stayed all day and normally hate that sort of thing. Also managed all of it just fine with just me and the toddler.
