We booked on Expedia and didn't expect the best room. Otherwise, we had done a lot of research (especially on tripadvisor) and expected a great experience.
Our expectations were mostly fulfilled although we had a tough first night (of a 2-night stay). When we arrived we were given room 1104B and upon entering the room we heard a fairly loud helicopter-like noise and the floor was vibrating slightly. After we complained an engineer came to our room and told us that there was a water pump near our room and it was pumping water to the next building. He said this would stop within an hour, but two hours later we had to complain again, after which we were promised that it would be turned off in an hour. However after falling asleep, I woke up at 2am and the noise was still going (my wife was able to sleep through it). We learned it actually was not a "temporary" noise but a permanent one, and the machines were right below our room. The lying by the hotel staff was annoying and we were not offered any apology but we did get a room change for the next day (to 3603, 6th floor near the beach side).
Other than this problem we very much like the hotel! What is said in other reviews is true - good but expensive food (although not extremely expensive as restaurants in Cabos go - a good breakfast buffet around $18 with taxes), nice newly built hotel, good pools (but the weather is usually too cold this time of year to use them), a great beach, and friendly people. The hotel, like most in Los Cabos, is full of Americans. Some people like that and some don't .... for us it did make watching the Super Bowl a lot of fun.
So, the lesson of this is that this is a very nice hotel and we would go back, but be careful about your rooms especially if you are booking through Expedia or a similar website. It seems that there is more than one water pump and so the safest bet is to avoid the 1st floor (any room with a 1 as the SECOND digit) and certainly 1104A or 1104B (I think another reviewer also gave some advice on this.) You may also hear other drainage-related noises (water goes loudly down the shower drain), so light sleepers should bring their earplugs just in case.
Whale watching: we did a whale watching tour ($55 per person and arranged by the hotel travel agency). It looked quite peaceful in the brochure and we boarded the boat at the Marina with the company "los Cangrejitos." While we did have the pleasure of seeing some whales, it was not such a pleasant experience since the motorboat was small and was frequently splashed with water as it buzzed through the cold wind and cold Pacific ocean waves. We arrived back at the marina quite wet, cold and happy it was over with. So if you want to see whales (between now and mid-March), check on what type of boat you'll have and if it will be an open one, dress warm and waterproof (including for any eyewear since you can't see many whales through wet glasses!). The company also did not have life jackets which didn't make us feel so great as the boat was rocking back and forth.
Taxis: As others have said, it is good to walk outside the airport to take a shuttle taxi which charges $15/person. There is not much signage but if you go out and to the right, you will see the white vans. It is a shared ride so they make a few stops. Going out of your hotel, you will probably have to pay $65 (for your group) so it makes sense to try to connect with others going to the airport. Taxis from the hotel to the marina are only US$6 (70 pesos).
Timeshares: We said No to the concierge after she gave the initial pitch on the benefits of doing a "tour" and we were never bothered after that.
Last tip: The exchange rate is actually around 11/1 but it is treated as 10/1 so you will save by getting pesos from an ATM. Not a big deal but for example on the departing taxi you can pay 650 pesos (around $60) instead of US$65.
