I'm still holding out hope that the horse pack will be a GP. I know it's unlikely but I'm going to hope until there is an official announcement.
I too saw the hints and was hoping the second EP of the year would be travel/hotels based.
I would like to see the return of 3 travel destinations like we saw in previous travel packs. I want travel based careers, ability to homeschool, and goals based on visiting specific locations.
As for the worlds, I would love to see Iceland, Thailand, Morocco, Australia.
I also think expanded archeology opportunities would be nice but maybe not within a hotels/resorts pack but rather a pack of its own.
