Yes, you are understanding that correctly. I've stayed at LA a few times. The King (King sized Bed) rooms are a little bigger than the Queens. Plenty of hot water and the food is delicious. The all inclusive is a good deal, ESPECIALLY if you drink alcohol.
To be fair though, breakfast is included in the non all inclusive price. The non all inclusive price is also covered by the CRT discount 25% off the weekly rate etc.

Oh, almost forgot, the Wifi always worked good for me and I've met a lot of cool people there.
The LA is my hotel of choice while in SJO.
