Hi Pete
Welcome aboard!
Sorry, I confess you've lost me. Where did you see complaints about Top River Pearl being noisy? I vaguely recall a vitriolic report from one guy who arrived there right at the end of the floods, late last year. Did he mention noise. Can't remember!
OK, let's take this back to basics. What is noisy? If you are going to stay in a village, you have to expect some noise - particularly in a Caribbean village. Tobagonians love their music and yes, you will regularly hear radios/music centres being played in ANY village in Tobago. Then there's the roosters and traffic, etc., etc. So, any village is going to be noisier than a completely isolated rural spot with no neighbours.
So, how about Top River Pearl. Well, first of all its on the back edge of the village, not in the centre. In fact, if you take the pier as the centre of the village, its about as far from the centre as Rosa's.
Is it noisy. Well having stayed there I can categorically state that I did not find it noisy. In fact I would have called it quiet and peaceful. Yes, I could hear the congregation siging in the church next door one Sunday, but I personally found that very pleasant (despite the fact that I'm not religious). I heard no loud radios/music centres and the traffic was minimal (the road ends just after TRP so there's nowhere for traffic to go). My only complaint on noise was the truck that insisted on clearing the public garbage bins just down the road at 6am once a week - but you would have that problem everywhere else in the village as well.
Please take it from me that within the constraints of being located in a normal Tobagonian village, TRP has no 'noise' issues other than those of guests with an axe to grind.
Take it from me, having stayed there.
