I'll have 2 weeks to dive next summer in North Sulawesi. I've booked a week at Kasawari Resort in Lembeh and want suggestions about where to go the second week. I'm looking for gorgeous reef diving--not too much current, if possible-- (juxtaposed to the muck diving in Lembeh). Which do you think is more wonderful--Bunaken or Gangga Island (or another spot I don't know about and which dive resorts would you recommend? Thanks.
