Need Help Filling in our Itinerary in Amsterdam

A fun activity that you and your family might enjoy would be to rent bikes for at least part of a day to explore the outskirts of the town or, if you're particularly ambitious, head north or south out of the city along some of the prettiest dedicated bike paths on earth.
About 3 minutes from your hotel is a place called Black Bikes, which is where we rented from ourselves a few years ago. The staff were quite helpful in suggesting routes and distances geared towards our level of fitness and degree of interest, and they offer a map of the various bike paths in and near the city which we found to be very helpful.
There are other bike shops scattered around the city, including at least one near Central Station - from where it's a short pedal to a cute little pedestrian/bike ferry across the river and the numerous bike paths in the poulder country north of the city.
Would be a very "Dutch" thing to do.

For eats:

• You must try a rijstafel (“rice table”)—an Indonesian smorgasbord. I like Long Pura and Blauw. I haven’t yet tried Aneka Rasa but will do so in April.
• For an interesting, little known lunch, try a lahmucan (aka Turkse Pizza). My favorite traditional turkse pizza is Leeman Doner. Effendy is great and is more of a hipster type place rather than old school Doner.
• Try cafe de reiger for a lovely traditional eetcafe.
• Stop by Lanskroon for stroopwafels. They’re made fresh each morning and blow doors off all the mass produced stroopwafels.
• Biertuin is my favorite gastropub. Their ribs are amazing. Three different locations.

For sights:
- You’ll love the Rick Steves Amsterdam self guided walking tour if you’re a history buff.
- You should reconsider going to Anne Frank House. It’s absolutely a must see, and I recommend reading her diary in advance.
- Visit Our Lord in the Attic—a hidden Catholic Church in the Red Light District.

We just got back 2 weeks ago, and also stayed at the Estherea. Loved it!!! The hotel recommended a different canal cruise, which you may want to check out. We did it and it was wonderful! If you go to the Reviews section here on the forum, you will see a few of my posts from our trip. It has restaurants, places we saw, what we did, etc and it includes a link for the canal cruise.

I highly recommend doing a walking tour your first day to get your bearings as well as to learn more about the city.

Make sure you make dinner reservations, even for not fancy places, as we saw so many people get turned away.

FYI at the Estherea, if you are opting for their breakfast, it is excellent. You do need to make a reservation time the day before for it though. So when you check in, make a reservation for the next morning and do that each day. It is very good and will not need lunches.

Some of my favorites in Amsterdam:
*Canal tour is a must! Great way to see the city
*Vondelpark (big green area for walking, cycling, picnicking, relaxing
*Climb up the bell tower in Westerkerk for good views over the city and a unique experience (right next to the Anne Frank House) reservations required.
*Indonesian food at Puri Mas restaurant
*Fresh stroop waffle at a shop

You might want to reconsider a trip to Keukenhof Gardens! They are only open for about 6 week/year. You can buy a combiticket for entrance and a bus trip (from Amsterdam or Schipol Airport). Bus drops you right at the gardens.

Have fun!

*Indonesian food at Puri Mas restaurant

According to Google, the restaurant is permanently closed and their website is gone.

The Westerkerk Tower, according to their website, is closed in 2024 for restoration.

We made reservations at Blauw for our last night.

Please note that your visit coincides with Remembrance Day (May 4) and Liberation Day (May 5). See my reply in this post for more information;

We are aware of the National Holidays on May 4 and May 5 and have tried to plan accordingly.
