CGlide has sussed out most of the boat race, but not all of it:

Some clips were filmed near forested land, especially when McCarthy pulls the old switcheroo (~40th minute) and then later on the 41st minute. I looked from Hollywood down to Key Biscayne, but I came up empty. I wonder if they filmed some of these scenes down in the Florida Keys?
This clip in particular is driving me nuts:
VANESSA´s HOUSE AT THE END, VERIFICATION SUMMARY + PICTURE PROOF
20 HARBOR POINT, KEY BISCAYNE
As @C Glide has still "location not verified" on this location website and the only proof discussed was hidden in the Group effort thread, I hereby summarize all proof& pics we have, as they are all scattered, the original house was destroyed&rebuilt completely new and the vintage proof pictures might get lost over the years.
