I think it is all about perspective. Everyone on here will have an opinion and keeping with that...here is mine
We always stay at AKR when we go. One trip, the weather was so bad we dove the south side all week. Bused over all week. Slightly off topic on same trip...this was before the airport in Roatan had radar and we ended up having to stay an extra 2 days before the weather would clear enough for planes to come and go. AKR was wonderful to us and took care of everyone there and no extra charge and other places on the island did not do this - so they got my loyalty.
We have dove both sides during the years and both have their pros and cons. I personally prefer the north side, but always love a ride over to dive Mary's Place - which is a must do dive.
I think that the north side has less divers and the south side has the cruise ship pier.
AKR has the marine institute and a great place to swim or dive with dolphins if interested.
Good luck and happy diving - DiverPam
