See, this is also frustrating: the family seems to have changed details as time went on. I don't call them out on this; I think it is probably part of the natural process of trying to make the story fit the abduction time frame.

In a letter to President Bill Clinton dated April 17, 1998, Ron Bradley states:
"When we awoke at 6:15 a.m., she was gone along with her cigarettes and lighter. At that time we were approaching the island of Curacao."
Approaching the island... Not docked at the island. This fits with the 10 miles offshore facts.

On June 11, 1998 her aunt wrote: " My niece, Amy Bradley, disappeared from the cruise ship Rhapsody of the Seas as it was in the process of docking on the island of Curacao on March 24, 1998."
You can't be approaching if you are in the process of docking and you can't be in the process of docking if you are approaching.

"Ron Bradley said he awoke about 6 a.m. and saw that Amy was not in the room or on the balcony. He went to search for her, and at about 7 a.m., he said, he ran into the ship's security chief, Lou Costello, and alerted him. He then returned to the cabin and woke his wife.
By that time, the ship was docking in Curacao. The Bradleys said they pleaded with ship's officers not to lower the gangway for disembarkation until their daughter was found, but the gangway was lowered."
So this apparently shows the ship wasn't docking until around 7 a.m.
We can infer she was no longer on the balcony while the ship was offshore, about ten miles. The ship was docking while her family was actively searching the ship for her.
To me, this is important to keep in mind. She was no longer on the balcony while the ship was offshore. Now, she could have been raped/murdered and smuggled off the ship after the ship docked (I'm not a fan of this theory, if anything, if she was killed, I believe she was tossed overboard)...
It makes it appear that Amy, as a trained lifeguard, would be able to swim to shore IF the ship was in docking procedures if/when she "fell off the balcony." It's an entirely different story to know the ship was about 10 miles offshore when she was discovered to be no longer on the balcony.
"Royal Caribbean's spokeswoman, Lynn Martenstein, would say only that the company had cooperated with investigators and did not believe foul play was involved. But an internal Royal Caribbean report provided to The New York Times by the Bradleys said that Bradley did not notify Costello of the disappearance until 7:35 a.m., by which time the ship had docked and passengers were going off for a day of shore excursions. It also said a cabin-by-cabin search was conducted almost immediately."
The passengers were leaving the ship by 7:35 a.m.
