Hello tonfromleiden and tim
Thank you for your suggestion and directions quoted here: If you want a nice boat trip, consider a visit to Kinderdijk and Dordrecht. Kinderdijk is justified famous for its impressive windmill complex; Dordrecht unjustified not famous for its wonderful position on a crossroads of rivers and a very nice historical centre
I skipped over Kinderdijk, (didn't know about Dordrecht - sounds interesting - will look them up) as I thought it was a bit too far for a return trip to Amsterdam as I need to go to Rotterdam but your directions and explanation to Kyle in a latter thread today makes it sound quite doable. I have my Chipkaart covering train travel as well so I am covered there.
I saw from your comments that Kuekenhof is very busy but that's ok. If it's too much I can go to Leiden sooner in the day. I'm expecting crowds! and plan to leave AMS early in any case and only during the week. I presume you take the bus from Kuekenhof to Leiden? There is an express bus apparently in the reverse direction according to RS guidebook. From Amsterdam I take the 197 to the airport and from there another bus to the gardens; and take the train from Leiden to Amsterdam.
I look forward to spending the day in Delft. I may have to skip the Vermeers unfortunately if I do the Kinderdijk junket...
I think I will be busy enough as it is. I do plan on walking a great deal in Amsterdam - I spent a day in Amsterdam on the way back from Rome about 3 years ago and wanted to come back as it had such a nice feel to it. (This was Nov. 1, cold and blustery - Rome was 30 Degrees Celcius when I left. What a contrast!)
Thanks again for all your suggestions. I really appreciate it.
