We're flying to AMS from Hawaii in mid-May. We arrive in AMS around 8A (have an overnight in SEA on the way, so hope to be fairly rested). Thanks to suggestions from another thread, we're basing in Haarlem for the first day and flying out to the UK evening of the following day. We scored a super price from Hawaii to AMS, thus the reason we're going this way.
We'd like to see some of the famous London landmarks (is Westminster a good option?), enjoy a musical at the West End, and then travel outside the city. We would love to go to Canterbury, head to Scotland and if possible, see a bit of Ireland, although we realize that it's not likely to work out.
We only have 7 days for the above, 11 days overall, including travel days.
What's not to miss? We're seniors, not drinkers and aren't looking for night life. A lot of walking and/or stairs could be a problem. Public transportation is our preference as are more local spots. We prefer traveling by train once in London and flying back to AMS for the trip home from wherever we are at that point.
I know this is a very broad request, but will appreciate all suggestions!
