Also dived with DiverLodge on a number of occasions.
Brill service--good staff and really friendly, i would reccomend them anytime.
did a Nitroxcourse a couple of years ago with emperor but not been with them since, i would be looking at the travel times
You are staying at the hotel with Diverslodge on the door step, climb outta bed eat and walk over to the diver centre---no waiting outside hotel for pick-ups and no being last drop off on the bus on the way back --i know what i would do.
hope this helps and have a great time.
