One benefit, stated plainly: a better place in the join queue when the server is full.
What you get: priority in the join queue when the server is full.
What you don't get: nothing else. No growth boost, no stat changes, no protected slot, and no ability to remove anyone who's already playing.
When it starts: VIP is applied at the next scheduled restart. No restart is scheduled yet — the exact time will show here as soon as one is, and your confirmation email will state it.
Prices include VAT. Cancelling stops renewal at the end of the paid period; access runs to the period end. Full terms are in the refund policy.
