And it's begun. The twenty-one sims of the Fantasy Faire are now open to the general public. Already some of the sims, such as Fairelands Junction where the main entrance is at (61/101/34), are a bit crowded. So expect some lag. You can find the SURLs to the other sims here (link).
Of the Fairelands Quest, the first part should be available in a few days, "Part 1 of the Quest opens Monday, 26 April and Part 2 starts Thursday, 29 April."
