First of all, this hotel may be "right on the beach", but it's not a swimming beach. Boats are docked there. If you try to swim between the boats (as we did), angry locals shout "danger, danger!!!" as they speed by in dingys.
The view from the hotel seems nice, until you discover you have to view it standing up. The hotel has no beach chairs or otherwise comfortable chairs (even in your room) to sit on.
Some rooms do not have air conditioning. We were forced to push four beds into a room which should have only held two beds -- without A/C. We had to climb over each other to get into our beds. Staff would not let us check into our rooms until after 4 PM, even though you could clearly see the rooms were ready (and empty).
The lobby of the hotel has an extremely annoying fake-Yosemite-waterfall plaque that makes artificial bird noises 24/7. We heard this all night long through the thin walls of our room and were driven to madness by the repetitive nature. It is like a tape loop of electronic tweeting. At other times, the TV in the lobby was going at full volume (staff occasionally stopped to watch soap operas). We turned it down twice and even turned the TV completely off at other times -- only to have the staff blast it again.
There are biting insects in the lobby. My legs were covered with new bites after writing in my diary for 45 minutes.
There is no hot water in this hotel.
There is no food or beverages available until the staff is ready to serve you at mealtime. If you are still hungry after your meal (as we were) -- too bad. There are no seconds or even refills on coffee.
In case you are not aware, you have to travel to different islands to snorkel, kayak, wind surf, etc. We assumed we would be able to do these activities near the hotel. You can not. You must book a boat to other islands in order to enjoy Los Roques.
I am not completely sure what people are complaining about. Posada Dona Carmen was much better than I thought it would be after reading all the negative reviews. The rooms are spacious, clean, with AC or fans. Rooms number 5 and 6 are beach front. They give breakfast and dinner. The food is better than typical Venezuelan posada food. meals were typical Venezuelan breakfasts, Arepas, cheese, soem kind of meat and eggs. Dinners were usually three courses, an appetizer, a main meal, and dessert.
The Posada has that main square on one side and the main beach (from whcih you catch your boats to the swimming beaches) on the other. That makes it ideally located for carrying heavy coolers to the boat, getting drinks or supplies from the local stores, and joining the party in the Plazas in the evenings. The most popular bar on the main island is right next door which can get loud, but our rooms were mid hotel and back so we never heard the revelry.
The people who rated this posada very low must not have traveled in Venezuela much. I think that the others who said they were disappointed were expecting something more like a Holiday Inn. We have been living in Venezuela for years and we thought this Posada was on par with any we have stayed at in this country.
You have to remember that Los Roques is generally very overpriced. beers are twice what you would pay on the mainland, ice is a precious commodity, and all lodging is at lest double what an equivalent lodge on the mainland would be. Its like that because they know you'll pay for it to spend some time in the beauty of the islands.
Of course the beach right in front of the Posada is not for swimming. NONE of the beaches on Gran Roque are for swimming. You are supposed to take a boat and go to the good beaches. And for the lady that said 'Angry Locals yelled from their dinghy's'; of they yelled at you you were being stupid and swimming in a dangerous area. Plus they fish for a living and you were disrupting their work.
I would recommend this hotel based on what you get for what you pay. You can get something a little bit better for a lot more money, but why waste you money when this is a perfectly good place for a lot less money?
