Just arrived from Bahia Principe Ambar.
I'm a Bahia Principe frequent guest (15 times in total) and was a returning guest at Ambar.
Also asked for Ambar 1 room but was given a room at Ambar 2.
Happy they did it.
Rooms are bigger, pool is more quiet and main restaurant is better.
You can still go and stay at the main pool if you prefer animation or go to the beach.
There are buggy cars from Ambar II to both the main pool and the beach.
