Travelling with 3 year old - Vienna or Copenhagen?

[Riseofthematriarchy]

Hello planning on a weekend with my 3 year old next month and wondering if anyone can suggest which is better.
I can't walk very far, 3 year old is super physical and loves being busy, we have a buggy and dietary requirements. Ideally somewhere we can walk around but still get back from and go to the hotel etc. Thank you in advance.

Copenhagen is very flat, has a lot of little parks dotted around for the 3yr old to run riot, and a great bus/tram/river bus network. You can buy a travel pass on your phone that covers unlimited travel so need to faff about buying tickets for every journey or feeling guilty about hopping on for one or two stops. From memory it worked out about £8 a day and included the tram to/from the airport. We definitely got our monies worth from it.

Vienna was fabulous with our three year old (and baby). The public transport is so good and there are so many kid friendly museums. We loved it!

I’ve lived in Copenhagen and been to Vienna only a year ago - I like both a lot but I personally would pick Copenhagen with a 3 year old - great metro, lots of nice play parks, big Westfield mall or fiskoterven mall if you get crap weather - you have marvellous Tivoli in the centre plus their food court . It also has a beach at Amager strand if you want a bit of sea air and it’s easy to do a nice trip up the coast on a train
