We stayed at Lago Mar for three nights at the end of February, 2008; two adults and one toddler. The good: the rooms are large, with good sized bathrooms, and the pools and beach are very nice and not terribly crowded; there is fun stuff for little kids (playset, swings, etc). The bad: the whole place just seems dark and damp. The decor is really dark and dated. I didn't see many staff members around. Food was ok but nothing special. Really annoying was that we asked for a pack and play and we were charged $20 PER NIGHT to use it -- we could have bought one for about as much as they charged us to use it - -and, of course, there was no mention of a charge when we asked for it at check in. It just seemed overpriced for what it offered. Despite the great location (at least as far as the beach goes), I would not recommend it and would not go back.

First before you drive to the hotel, go on to google etc. and get yourself a detailed map. The hotel is located in a residence area.
The hotel was very clean and had large rooms. The bathroom especially grand. There a lighted make up mirror and a shaving mirror.
There is free wireless interect. The hotel has old European feel.
The staff is very friendly. We eat in the dining room and had the Early Bird Special Soup or Salad and a choice of four entree for
$16..99. Yes there is an 18% Gratuity add on to everything.
I brought a bottle of water for $3.50 (500ml) and there was a Gratuity added on to the bill.
ALso ate the Sofa shop, the omelets were done in a microwave.
On our last morning we had a buffett breakfast. Yogurt, cheese,
cold cuts, plus a custom omelet station. Plus you would pancakes as well. The pastry was very limited and stale.
The beach was very wide and good for long walks.
There are play structures for children as well.

Stayed at Largo Mar as a pre to our cruise, next time will stay as a pre and post to our cruise. This is a “family owned” business, which is a plus to me. The complex is beautiful, quiet, and classy all in one. Not cheap but a great value none the less. Directly on the beach, this place is all you could ask for and more, old time Florida. Simply put sheer perfection.

Very courteous reservations staff convinced us to try Lago Mar for a long weekend in February. First impression was of a grand old resort, dated but not shabby. The grounds are lovely and the beach and pools first rate. A note on the "Olympic size" pool: it is just a 20 yard pool, and it is divided in half, making swimming laps impossible. When asked to take down the rope to allow laps, I was informed it was not allowed. So, don't plan on using the pools to do anything but splash around a little. We stayed in a one bedroom in the older section. Yes, it had outdoor entrances and a very old elevator, but the room was nicely done and the view of the pool and ocean very nice. The kitchen was the most disappointing element, very small, dated and equipped with just one knife (and a butter knife at that) and a few utensils. Coffee maker was old and made only very weak coffee. It would have been a nice touch to have hot coffee in the lobby in the morning, too. The nearest Starbucks is a 5-10 minute drive away.
The pool and chairs are nice, the spa small, but adequate. The workout room could have been bigger, but served well enough. The food in the dining room was just okay,but the service was friendly and savvy. The concierge suggested a terrific restaurant for a night out and we loved Grille 66.
I don't think I would hurry back there, but if I were in Fort Lauderdale for any reason, I would be fine with staying there again. Room rates exceeded $400, so I would probably check out the Marriott Harbour Beach next time. But, given that I had read all the Trip Advisor reviews, I was not disappointed.
