I think hotels/resorts would be fun. I loved resort owning in the Sims 3. The hope is that they will pair it with casinos and houseboats. That would be an awesome pack. I was slightly disappointed with the wedding pack in that the love tree didn't have animations, the lighthouse didn't have any, and the waterfall didn't have woohoo. If these are pack specific then I don't think lighthouses should be included in other packs. They are pretty, but a waste with no interactions.
Also, banking could be introduced as a patch that included the system, nonplayable workers, and loans(tie in with college). If you get the Hotels combo, then the jobs in the bank become playable.
