The 2nd beta, I'm seeing as The Celestial Islands + Minor town + The Big City + two other towns to the south + Jailbird Island. The third and final beta for the Summer installment would be the remaining Big City park/cave, the remaining two towns to the north and all of the Highlander Pass. So, the final beta would be approximately 5 locations(six if you include the revisits to the big city) and one of the locations being four maxed out maps in size. A good chunk, I'd say.
