Gear Up for the Hot Time 3 Event

By 'in town', do they mean in any town, or just the major ones (Victoria Island, Orbis, Leafre, and Ludibrium)?

Wouldn't be surprised if it was actually the latter. :/

I'm worried about this too. What about towns like Herb Town, Aquarium, Ariant? are they considered major towns?

To be safe, i might just go to Henesys on a weaker character, open it, then log out and go back on my high level characters to make use of the 2x EXP event.
