I'm cheap and just trying to see if I can get this all done in 1 day with a 1 day London Pass thing (I'm staying in London for 4 days) and have other things I want to do those days:
Tower of London
London Bridge Experience
River Thames cruise
I have been to the Tower and Windsor before but I have a feeling it is too much trying to get Windsor in.
I figured Tower would be 2 hours, Experience 1 hour, one way cruise 1 hour, Hampton Court 2 hours, Windsor 2 hours. Of course none of this includes transportation and lunch! It's just me going so I can do things at my own pace.
