Everything a membership unlocks:
Ad-Free Play Members never have to see an advertisement on WarLight.
Full Ladder Access Members have full access to all ladders, which are competitive arenas where players compete to see who is the best. (can be unlocked through leveling up though)
Bomb Card Members can include the Bomb Card in games they create.
Create 20 player games Members can create games with up to 20 players. This can be any mix of AIs, open seats, or other players (they don't have to be members.) ((you can actually get up to 40 with levels, but it won't max you at 20))
Extra Vacations Members can take up to 7 vacations per year. (I think you can get 5 from levels?)
Recent Games page Members can view the Recent Games page to see games other players are playing.
Open Games Members can advertise up to four games on the Open Games section at once, whereas a non-member can only advertise two.
Honestly i wouldn't suggest buying a membership, unless you love this game and want to help support it. (or if you are super rich)
Basically how a vacation works is that you won't get booted from a game (mulit-day), so you won't have to worry about taking your turns. Vacations are at most seven days. then after the vacation (either by the time running out, or you taking a turn) you will have an hour before you are booted. So per year you can have 49 days of vacation (if they are all seven days). Also should be noted that some games do not respect vacations and you can be booted. (it says so in that games settings.)
Accounts are never deleted.
