First, let me get the obvious out of the way, and tell you that the resort is incredible. It was so nice, and so fun. The beach, the pools, the on-site snorkeling, the Disney character experiences - everything. It was, without a doubt, our favorite resort. There's no shortage of information about the Aulani online, so I'll just share a couple pictures of our family, and then move on to the timeshare analysis.
For us, we LOVE using our Disney timeshare, and with little kids (3 & 4!), we know we have a lot of Disney trips in our future. I calculate our break-even is about 8 years (4 trips), and I have no doubt we will take at least 4 Disney trips over the next 8-10 years. Sometime in the future, we also plan on renting our points, and using the proceeds to off-set the cost of a Disney cruise. It was a great Mother's Day at the Disney Aulani resort, and we cannot wait to get back there soon!
