A. This shot of a hotel in Miami Beach was used as an opening/establishing shot for the wedding scene of Dexter & Rita, in the Season 3 finale, "Do You Take Dexter Morgan?".

The action then cuts to the actual wedding location in Southern California.

The wedding invitation read simply: "Four thirty-seven North Hialeah Drive", but that address doesn't really exist.

In reality, the white hotel (with the yellow cone) shown in the foreground is the Royal Palm Hotel, which can be found at 1545 Collins Ave, in Miami Beach, Florida.

But for the record, there are actually two buildings shown above.

The large pink & blue building seen behind the white hotel is a condo named Fifteen Hundred Ocean Drive, at (appropriately enough) 1500 Ocean Drive, Miami Beach, FL.

The camera is looking south/southwest.

Here is an aerial photo of both hotels. And here is a map link.
