I hate to rain on your parade, but common sense is not always used in these cases.  It will come down to what the police decide, so let's hope they do a proper risk assessment, which is all any of us can really ask.

Well here I am at the pool in Dominican sipping my cocktail. I was a nervous wreck all the way there on the plane and at the customs (quite intimidating now, they have lots of glass booths and they were scanning everyone's passport and taking everyone's fingerprints) but when the lady scanned my passport she didn't even bat an eyelid and stamped it no problem so I suspect there was absolutely no notice sent out by UK NCB.

Now I can relax and enjoy my holiday! 

Just to note though that I asked my PPU officer about the notification he submitted for this trip and he actually confirmed to me in writing by email that he submitted me as a LOW risk with "no specific intelligence) so obviously if you are a medium or high risk then the dominican republic could still be dodgy. 

Hope this helps anyone planning to go there! 

Thanks for the really helpful update, and have a fantastic holiday!
