We stayed a week at Tom's place on our honeymoon. It's a very close drive to anywhere you want to be in Wailea, and Tom's unit is clean and very spacious, with a prime dedicated parking spot in the shade super close to the unit. That parking spot is very nice to have! This unit is a good way to stay in Wailea at a much more affordable price point. Tip: definitely check out the Island Gourmet small upscale grocery store a few minutes drive away at the Shops at Wailea for fantastic (and affordable!) pre-prepared meals right down the way at the Wailea Shops. Great poke, sushi, and lots of other easy quick meals. That made our trip so much easier, especially since we're not dining indoors still. Tom's unit was a good place for us to explore the beautiful Wailea beaches with only a very short drive. As others noted, Tom's unit is right across from the pool. We didn't use swim there since it was fairly crowded the week we were there, although there is a second pool on the other side that we could've tried if we were really wanting to swim. We chose to swim at the Wailea beaches (Polo, Maluaka, and others) instead which was great. There was a turtle that swam by us at Maluaka, and we did some snorkeling there too after renting gear at Snorkel Bob's right near the condo. The snorkeling was excellent.
Regarding staying at Grand Champions more generally: If I were to book again in Wailea due to my accessibility notes below, I'd likely prioritize something off of Wailea Alanui Drive like the Ekahi or Elua villages instead of Grand Champions if I was able to find a similar or bit higher pricepoint because it would give easier access to the paved Wailea beach path, which is where we ended up most evenings before/at sunset. It's fantastic.
Some accessibility notes for anyone with mobility aids or families with strollers about staying here/at Grand Champions more generally: note that there is no sidewalk (and no curb cut where the sidewalk ends exiting Grand Champions) between Grand Champions and Wailea Ike Drive, which is the primary route people walk to get down to Wailea Shops and Wailea Alanui Drive. I use a mobility scooter, and it was frustrating that we were so close to the area but couldn't access it without a car because of this gap in sidewalk between Grand Champions and Wailea Ike Drive. (Also you are not permitted to go onto the golf course path from the Grand Champions grounds, so that won't get you paved access down to Wailea Alanui Drive/Wailea Shops either.) Lastly, there is a pillar supporting the second story unit that is on the sidewalk as you enter Tom's unit; if you have a mobility aid or stroller that needs to come inside the unit, it may be tough to fit it past this point. I was actually able to carefully squeeze my scooter past it, and stored my scooter outside the whole time and it was fine. This unit is not advertised as being accessible so everything was as described in the listing, no issues there, but given the limited availability of units that are accessible and the fact that this unit is ground floor, I wanted to note this. Hopefully it helps someone!
