I’d like to know if there is some way to add or remove rooms from in checkout page. I don’t mind to use any php code, but I’d like to know if there is some hook that already allow something like that. Thanks in advance.
Unfortunately, there is no such option by default, it would require plugin custom development. We do have such a feature request, however, it has not been quite popular to the date. I have added your up-vote to it as well, in case there are more similar requests from other users, we might consider implementing such feature in one of the plugin future updates.
Anybody else who also needs this feature feel free to let us know by commenting this topic.
