DBF and I just spent 6 days and 5 nights in Cabo San Lucas at the Riu Palace all inclusive resort, and here's my general overview of my first vacation experience in beautiful Mexico.
1. Riu Palace. It's reasonably priced, with great ocean views (but you can't go in, the water is too choppy here). The minibar is stocked every day and the A/C works great. Front desk is helpful, until you have two friends that are staying at the Riu Santa Fe (in the same lot, same company). They're not allowed anywhere past the the entrance of our lobby. Not in our bars (even if they don't drink), not in our private rooms. The front staff then gets quite rude and throws out bs legalities. However, we are free to walk to the Santa Fe for their amenities and are welcome in any part of their resort. The buffets are horrible, but the pico de gallo is fresh and delicious, and for the reservation only restaurants on the resort--I don't recommend any. I got a mild case of food poisoning from two little slices of raw fish in the "Japanese" restaurant. There's consistency though--nobody can cook red meat. DBF asked for medium rare, and I asked for rare. We received medium well and a well done/leather. The wait staff obligingly removed the leathered rib eye and came out with a steak that had been grilled on each side, and then served. I love bloody steaks, but this was beyond rare. Cold is not good. Eat off the resort if you know what's good for you. In fact, if we ever return to Cabo San Lucas, we'll be staying at a different resort--something closer to downtown, something not all inclusive, and definitely nothing from the Riu family of resorts.
2. Food. We asked the locals what their favorite taquerias were, wandering away from the touristy areas into the more shady depths of the city, hungry for some good tacos. Taqueria El Conde is our favorite. Their al pastor tacos are to die for--rich, bright flavors and tender pork. The lengua is buttery, and I couldn't ask for better cabeza. From the main entrance of Puerto Paraiso mall (where the Haagen Daz is), walk across the street and one block forward, then take a left and walk until you see Taqueria El Conde. Order 4-5 tacos, a 500 ml Mexican Coke, enjoy. Repeat for remainder of trip.
3. Shopping. Head to downtown, go to the Puerto Paraiso mall and head straight into Luxury Avenue. Apparently there's an Hermes boutique under construction, but open are Chopard, Cartier, Fendi, Ferragamo, Carolina Herrera and Swarovski boutiques. Stock up on beauty needs at UltraFemme and satisfy your jewelery and watch needs at UltraJewels. UltraJewels was our favorite for many reasons. The first of which being that the service is impeccable, never pushy, always helpful. Secondly, they had collected quite a few hard to find and beautiful watches. We walked out with a PAM 292 (the black ceramic black seal) and a PAM 282 that I could not take my eyes off of.
4. Things to do. We rode horses on the beach at sunset and swam with dolphins. There's parasailing, outdoor adventures, waverunners, and glass bottom boats that will take you to the famous arch, lovers beach, or divorce beach.
