Do not let the trobles put you off we went twice and both times there had been fighting, no troble what so ever i felt very safe including on the trips, the tour guides are very trustworthy and know where to go and where not to go. you will have the trip of your life we did. we also did the five day tour the first time and used beach boys the next visit and found it to be just fab.
Very long flight check to see if you have to land in the maldives as this adds another hour or more, get extra leg room seats well worth the extra money. take small gifts for the local children, pens, felt tips ect as you will be asked for things such as 'school pens' give the kids a few rubies 50p worth can feed a family all day and watch thier faces they beam and it is so worth it.
Go to the elephant sanctuary do not miss it, take your camara and tissues, the sight of seeing over 50 elephants bathing in the river a few feet away brings on the tears or pure joy. ps you also need them for the loos.
have a great time i will be going back myself in the near future.
