Just came back from a three-night stay here! Arrived on a Sunday afternoon and the reception employee recognized my name as a guest with elite status. I'm not sure if it was because it was a relatively quiet period, but I was provided with breakfast for two each day AND club access, which I understand are typically Globalist benefits. However, I did book a premium suite (Executive Suite with Pool 1 King Bed) with Cash + Points rate: 9,000 points + ~925 MAD (~92 USD at time of writing) per night for a Sunday-Wednesday stay in late May. This felt like a much better rate than the 18,000 points per night for premium suite awards (which is still pretty good!)
Requested an airport transfer in advance from AGA to the hotel for 450 MAD. The drive was about an hour with some traffic on the main road leaving Agadir and heading up the coast.
The suites with pools are situated on the far ends of the property, but just a stone's throw from the main resort building. There seem to be four suites with pool in total, with two on each side sharing a building. Pool areas/backyards were separated by some tall plants. They're exactly as pictured in the photos on the hotel website and were always clean and well looked after. There are also two TVs, one in the living room and one in the bedroom.
Restaurants
Sud Km 17 - ate here our first night, a nice sunset dinner on the beach. Food was good but nothing spectacular, service was not particularly attentive.
Citron Brűlé - ate here most of the other times. Breakfast buffet every morning was large and spectacular, in fact seemed like way too much food for the number of guests there at the time. But I think the spread is pretty standardized so they probably just have the same stuff made every day. Omelette/egg station available! Dinner here seems to be a buffet on some but not all nights. The buffet was available on a Monday night (350 MAD/person) and then only a la carte menu the following Tuesday night.
All of our food was good and definitely restaurant quality, but the prices reflect that - certainly very much higher than more local restaurants to the area. Dinner for two with drinks and dessert probably in the 75-100 USD range (that's my currency of reference).
Club/Lounge - open 12-8pm, tapas served 6-8pm, alcohol served 5pm onwards.
Shuttle - runs twice a day to both Taghazout and Agadir. We only took the shuttle to Agadir and that drops you off at Place al Amal. For Agadir, the shuttle leaves the hotel at 9am and 1pm, and returns at 2pm and 5pm, at the time of writing.
Water quality issues - I did read up on the TripAdvisor threads about the water quality of the ocean but can't really make a comment here. We went down to the beach once and I dipped my feet in the water but we didn't do any swimming and stuck to the hotel pools. Nothing notable that was airborne or anything though. My partner and I weren't sick while we were there and seem to be fine now about 72 hours after leaving.
General thoughts - the hotel was always fully staffed with people at each station (restaurants, club, lobby bar, pool, beach, security, etc.) even though I didn't see more than ~50 other guests while we were there. Service was always friendly and professional. This area is certainly seeing a ton of development in the last 5-7 years and for several years to come. We did walk by the Fairmont (there is a beach promenade that goes for several kilometers along the water in the Taghazout Bay development area) and it looks really nice. I'd definitely stay at the Hyatt Regency Taghazout again, it's certainly well worth the cost and isn't particularly difficult to get to. It did kind of feel like a copy/paste of a Hyatt Regency template into the Moroccan landscape with some decorative objects in the rooms and common areas to suggest you were in Morocco. But I can't say I had any complaints about my stay either!
