This last time we stayed in C14. I we have also stayed a few times in other units like C12, C10, C11 and C15. We were put once in the A units and got moved. The unit was very dark, way too much knick knacks and other breakables for kids to be staying in.
A4 and A5 are probably our favorites but anything A1 thru A10 is nice.
B18. One bedroom was in the back so had a good breeze at night. Might have concern with upstairs units where bedroom is the loft. (hot air rises)
Re: temperatures in August. We were at Napili Point in November, but it is my understanding that the day and night temperatures do not change much between summer and winter.
We were a bit concerned about not having A/C, but the cooler night temperatures and on-shore breezes didn't require A/C. Day and night temperatures were very comfortable for us.
If you can get to the Lahaina Luau, you won't be disappointed. Book tickets early!
Can't remember the exact number, but it was on the B level - I think that most of the B level units had one bedroom. Our 2 sons and our relatives had units on the upper levels - all had 2 bedrooms. All were very well appointed and had tremendous views.
I wrote a review (I'm pretty sure for TripAdvisor) after our stay in December and mentioned the unit number B...... which had many deficiencies. Our brother in law stayed in a B level unit beside ours, and it was very nice and well-appointed.
I believe it was b21. B is the middle level.
We had two units and both were clean and well maintained. call the manager Rod Kelly. Rent your unit through the management. There are a few units rented by owners directly. These units are not maintained by the management, and I heard some units are poorly maintained.
