Thanks Browtal. I stayed in a small hotel beside Paddington Station (£120 per night for a room for 3)so we walked through Hyde Park in the mornings to get towards the tourist areas. Beautiful walk.
We went to the Tower of London the first day, Friday, after we arrived. The guided tour was brilliant. We only got to go to the Crown Jewels half an hour before closing time but by then the queue was gone and we were nearly on our own. There is a charge to get in. On Saturday we went to the Imperial War Museum the second day. We took plenty of breaks so that my youngest boy who’s 9 wasn’t tired. In the afternoon we walked around The Mall, Buckingham Palace, Westminster and Tower Bridge. That night we went to Simpsons Restaurant and it was great. It’s expensive (around £50-£60 a head) but it’s a memory for the kids. Sunday we were at the Natural History Museum when it opened and stayed ‘till around 2. When we were leaving there were over a thousand people queuing to get in. We went down Carnaby Street after that and had our lunch in a gourmet burger place before getting a taxi back to our hotel to collect the bags and walked to Paddington to get the Heathrow Express back to the airport.
The flights are expensive, well over €100 each, but you can buy the train tickets at Dublin Airport at a discount (beside the departure gates). Adult return is £25ish and children were around £15 each.
It really is a great city; lots to do, easy to get there and really nice people.
BTW, we went to Legoland in Windsor last year and that was fantastic as well. I preferred it as a holiday to Disney World in Florida.
