It is not unusual for an activity to take place on specific dates (for example, an event will consist of 3 or 10 concerts on specific dates) or for you not to want to publish them and put them on sale immediately after they have been created (e.g. you prepare your summer offers in winter and don't want to make them public until spring).
So there are two possible scenarios:
1. Your package is visible and bookable all year round
You have absolutely nothing to do: simplysave your package and move on to something else. That's it! It's on sale: Congratulations!
2. Your package is based on different dates
Click on Define special dates
Set the publication dates (visibility) for your package
Thenset the possible booking dates for your package
You can create a package that can be booked from 1 July to 31 August, but only want to publish it (make it visible on your booking engine) from 1 April.
Now that we've finished, why not share all this on your Facebook page?
