This Plan2Book demo is a real time example of De Gouden Kooi and Escapepool.
De Gouden Kooi operates several escape rooms at two locations in Mechelen, Belgium. Escapepool operates one escape room in The Netherlands.
At De Gouden Kooi, the choice for the customer between planning and booking was fully incorporated into the website, while at Escapepool it is the web app itself that displays the choice to the customer. Both options are possible.
You can take a look at both websites to see how Plan2Book was implemented.
You could start a planning so you can see for yourself how it works. Of course you don't really have to make a booking.
De Gouden Kooi chose to implement Plan2Book in Dutch and English, Escapepool only opted for Dutch. More languages are available.
