I looked but here is not even one week in Aruba that is not an all inclusive available in weeks so I can't confirm how many TPU's are needed.
I don't want to be the bearer of bad news but it is nearly not possible for you to get a 2BR for Divi Aruba Phoenix Beach Resort, #4032.
1- There are not many 2BR units in this section of the Phoenix (#4032 is the original Phase 1). I think there are less than 10.
2- July is a popular time in Aruba and lots of owners use their week or rent it out if they do not.
3- Divi Phoenix was also sold as an RCI points ownership so when an owner does not use their week it is usually in points inventory only.
The 2nd phase of the Divi Phoenix (Beach Villas at Divi Phoenix, #8729) are primarily 2BR lockout units. However, my understanding is they were all sold as RCI points or in their new points system (which uses Interval). The only time it will become available as weeks if the owner disenrolled the week from the RCI points program.
While you can get lucky, I would add additional resorts in Aruba but Aruba in weeks is very scarce. Much more availability in RCI points.
Using points, I see lots of availability (but not a lot of full weeks) in July and August for studio and 1BR for Divi Phoenix (#4032) no 2BR's at all. All are labeled as "RCI Points"
The same for 2nd phase of the Divi Phoenix (Beach Villas at Divi Phoenix, #8729). Some 2BR end of August. All are labeled as "RCI Points"
With points, Aruba gets pretty booked at 10 months out as soon as inventory opens.
