From the EQ2 Forums:
What if we told you that we’re offering DOUBLE EXPERIENCE to our All-Access members for a whole week?
The double experience bonus for Adventure, Tradeskill and AA XP will turn on at noon PDT* on Friday, September 18, 2015 and will last a full week! This means you have until noon PDT on Friday, September 25, 2015 to fill up those XP bars!
The Double XP bonuses will be available for All Access members on all traditional servers. While the bonus will not be available on Stormhold and Deathtoll, there are still exciting adventures awaiting All Access members on those special servers. Remember, you must be a member to access Time-Locked Expansion servers.
