Thanks for clarifying what G village is. As a courtesy to those who are trying to help you here, can you please use the actual names of places you want to visit, instead of made up abbreviations? That way those who want to assist you here don’t have to guess what it is you’re asking about. So please use Giethoorn, not Geithoorn village and definitely not G village. And by K garden you probably mean the Keukenhof? Please use its proper name. Thanks!
That said, let’s get back to your trip.
It only takes 25 minutes by direct bus to get from Leiden to the Keukenhof, not 1 hour. Visiting the Keukenhof as a day trip from Leiden is so much easier and quicker than having to check out of your hotel, travel to Lisse with your luggage, find your hotel to drop your luggage and then go to the Keukenhof. But by this time it’s probably too late to cancel any hotels?
Where in Belgium will you spend your first night?
It seems that everything is locked in because you already booked hotels and activities, but it would have made more sense to go straight to Bruges, spend 2 nights there and go to the Netherlands. This would bring the Netherlands part of your itinerary forward by 1 night. The extra night at the end should be spend in Amsterdam, because 2 nights isn’t nearly enough.
Also, why have you booked both the Anne Frank House and the Corrie ten Boom house? They are somewhat similar places, but I found the Anne Frank House to be much more moving. At the Corrie ten Boom house I felt that they put too much emphasis on the religious work of Corrie after the war. I was warned about this beforehand, but it still surprised me how little we actually learned about the hiding place.
Since you only have 2 days in Amsterdam, I would skip going to Haarlem and just spend your entire 2 days in Amsterdam. You won’t even scratch the surface of all you can see and do there.
