I spent several days at Costa Real Cabo and my advice is don't even bother wasting your time or money. I'm not sure where, exactly, to start, but the best place is probably the lobby where immediately upon check-in you will be assaulted by aggressive people trying to bully you into attending (4-hour) time share presentations in exchange for free pirate ship excursions and sunset horseback riding. In fact, you can't even walk THROUGH the lobby without being harrassed by numerous vendors at any time of the day or night. Being hassled in the streets is one thing, and somewhat common in Cabo, but in the LOBBY of the hotel?? And in the elevator, and at the pool, and in the shops, and probably in your bathroom if they could get a key from the front desk.
All-inclusive food and drinks at Costa Real Cabo means you don't get what you don't pay for. The drinks at all of the bars were completely watered down. Your best bet for alcohol is to order beer since they can't pop the bottle cap and dilute the contents. The food on the lobby restaurant menu was okay, but the buffet food was less than memorable and contained enough MSG to make a Chinese restaurant proud. A word of caution about the food on the second-floor buffet -- be prepared to share it with the pigeons. The birds have free access to all of the food on the bar, and the sight of them landing on the dessert platters and digging into the key lime pie was a terrific source of entertainment for everyone who ventured in there (by the way, it's your only option for breakfast and lunch in the hotel). The buffet servers stood by and watched the birds, and shrugged when one of our group suggested they remove the pies the birds had been jumping in and out of. I'm not exaggerating.
Eating dinner in the lobby restaurant is no guarantee of a quiet meal, either. Children wander off the street through the lobby bar and restaurant and tug on your elbow every five minutes at the table trying to get you to buy whistles and jewelry. They also wander in and take regular advantage of the unattended 24-hour "snack bar" which consisted of cold hot dogs and a chafing dish of chicken fingers.
The rooms are clean enough, if you can get room service there to clean on a daily basis (we had to call the front desk at 6:00 PM one evening and beg them to send someone to clean our room), but be prepared to walk a mile or more through long winding hallways to get to your room, and, when you finally get there, don't expect a good night's sleep on the beds, which are, literally, as hard as concrete slabs. The front desk staff were casual and unconcerned. They explained to two of our guests that their toilets kept getting clogged because the plumbing between the bathtub drain and the toilet pipes was faulty. They didn't offer to move the guests to another room, or to fix the toilets, but they were helpful enough to leave plungers.
This hotel (the "Resort and Spa" moniker is one VERY large leap of imagination) is probably a safe bet for non-discriminating college students wanting to drink large amounts of anything alcoholic on spring break, but if you are accustomed to even a shred of comfort and class, look someplace besides Costa Real Cabo. You couldn't PAY me to spend a single night there again, and if you're considering the place for business purposes, spare yourself and your company the embarrassment. Your clients will thank you.
