MC,
Sanur tips:
1. take a big kite (refer my avatar FBK), 12 will be ok some days but have a 15-17 backup, not everyones cup of tea but why waste the opportunity to kite in the tropics
2. flatwater on the lagoon but just kite out to reef (pretty shallow) for small but fun waves
3. keep an eye out for and show some respect to the balinese fishermen and their floats, they hit the lagoon as the tide drops, walking out into the lagoon to fish
4. watch out for the euro kiters cause they cant see anyone else, some sort of tropical sun blindness and spatial awareness disability I believe
5. make yourself aware of the tides as the lagoon can get very very very low
6. be friendly with the local balinese kiters and they will return the favor, you'll see three distinct kite schools in the southern end all a short stroll from the mercure
7. mercure's a great holiday choice its a little slice of europe in bali, you'll figure that out later
8. all the warungs/eateries on the beach along that stretch are great to eat at, head down at night and dine on the sand, food is just as good as jimbaran bay.
Seminyak & Canggu on westcoast arent that remote but other spots may be.
Might not be epic location but you'll definately have a great time.
