HMBotel notes for choosing your ticket
Compare the inclusions above with your plans: admission, a guided visit and a combination ticket may cover different services. The venue name alone is not enough to compare them.
Check the meeting point and arrival instructions before adding another activity. The displayed duration describes the activity; plan travel from your hotel and your return separately.
Booking and payment take place with Tiqets. On that final page, confirm the date, participants, visit language, final price and cancellation rules; an indicative HMBotel price is not a guarantee of availability.
