I am choosing to leave the prices out of the invitation. My main reason is because I want people to have options in terms of # of days they stay and room upgrades, etc. I am not going through the trouble of listing that so they may discuss that with my TA when they contact her. I am also doing passport invites but I want them to stay classy and refer them to the TA. My close fam already has an idea of how much it will cost.
Also something to consider, if you provide prices, it may lead guests to consult you and not you TA which is a pain as well.
