The Grand Champions location is a great jumping off point for a Maui adventure. The unit is spacious and could easily fit a family of four, though it was just me and my partner. I truly appreciated the customer service from CB including a descriptive email on Hawaii COVID-19 protocols. The unit has a full kitchen, large living room, two bathrooms, and a nice view of Haleakala from the lanai. All in all, if you're like us and just needed a home base to relax in-between day trips, it definitely served its purpose.
There are a few things worth noting. It is a bit further from the beach than we anticipated. The closest beach is Ulua beach which is about a 20-25 minute walk. If you cut across the golf course, it's a little shorter. We had some minor issues with the plumbing and light fixture on the lanai which CB responded to quickly, sending a handyman out to fix these the next day. However, we did notice a cockroach and what appeared to be rodent feces on the fold up beach chairs which I did not hear back on. This wasn't a huge issue for us as we hadn't planned on using them, but worth noting since it was listed as an amenity.
All in all, I would still recommend this location if you're looking to stay in the Wailea-Makena area. If you don't mind not staying right on the beach, it's easily 2-3x the size of a hotel room you'd get at a similar price and has great service by the property manager.
