Do all LHC maps have party bonus?

Moment ago some dude came to the map our party was in and said that there is no EXP bonus in the first map with crocodile mobs.

However, ellinforest people seem to train at Crocs... Unless there is more than 1 map of them?

There is exp bonus.

Easy way to check is, when you first enter the map, if there's EXP bonus, then bright yellow letters flash across the top middle of the screen.

There definitely is a bonus.

The amount you get is pretty ridiculous. We had hs and a full party. I did family buff and bought a 1.5 card and I was getting 250k per bearwolf that I kill.
