Is it possible to NOT show a Price Package on the front-end?

Hello again,

I would like to implement the following feature.

1) In a certain CPT I would like to have a special price package only admins (so in the backend) can use. So any user from the front end can’t choose that package.

Is read something about hiding this with CSS, but I can;t find it anymore. What code should I use?

The price package I want not to be displayed is the “Special Museum & Attraction” in the gd_place (Things To Do) CPT.

2) Is it possible NOT to claim a certain category within a CPT. In this case the categories Museums and Attractions in CPT “THings To Do” (gd_place)

Many thanks in advance for your help….

Cheers, Jan
