couple things

1. regarding visibility = every forum I've ever seen that has VIP section has perks hidden, that seems to be part of the allure (side note a lot of people wanting to be mod has the same reasons, hidden forums with juicy gossip lol). I see no reason for needing to be aware of offers, UNLESS primary access is by payment (so buyers remorse, refunds etc isn't an issue. However, donations are different then buying access so if donations are a need, visibility still isn't a need as donations are voluntary support not a purchase)

2 Speaking of a hidden forum, thats a great place for VIPs to share their ideas and speak in a private place from regular members, a must imo

3. Unique games (types, buyins, tournaments) in the poker client, skinned diff for VIPs

4. Unique PO VIP freerolls on poker rooms, with different games and higher $ amounts

5. obv bigger and unique point gaining options

6. ways to interact in unique ways with members (special VIP bounties for members, etc) make it exciting for the rest of members, something to try to obtain.

I may think of other things but there's a start
