The Beatles had a police escort throughout their stay in the form of Buddy Dresner. This included having a meal at his home, shown here on his son's website. Buddy's wife Dottie was quoted in this article in the Fort Lauderdale News, 26.10.86:
The Miami Herald, 8.12.85 (by Joel Achenbach) and The Palm Beach Post, 13.4.90, had good interviews with Dresner:
Buddy's son speculates in the interview that the line "And so I quit the police department" in 'She Came In Through The Bathroom Window' may have been inspired by Dresner being ribbed by Rickles in that performance. It is supported by this out-take (at 1:20 "get a job cop" is a piece of banter that The Beatles might have used to tease Dresner in Miami) and also by Paul's comments on Rickles here. Buddy also states that one of Ruth Regina's jobs was to blow-dry The Beatles' hair after they came back from the beach or pool and took showers (Regina, whose salon had been in Miami since 1948 and was based at 7437 Collins Avenue, had been contracted by CBS, and would subsequently work on the Jackie Gleason American Scene Magazine show after it switched to Miami in 1964: Miami Herald, 8.2.64; Miami News, 27.12.64). Another of Regina's roles was to put Cynthia in a wig when she needed to be disguised.
Buddy claimed also that the hotel rooms were allocated by CBS and that The Beatles ate dessert before the other courses instead of at the end. They were unfamiliar with gefilte fish. John discussed the Vietnam War with Buddy, who was hawkish at that time and blamed the British for their treatment of Israel in the 1940s. Ringo did not like swimming or spicy food (perhaps related to his childhood illnesses).
This collection of photos comes from the Miami News, 4.2.84:
There are more photos on Barry Dresner's website here.
Ringo took photos himself but this one has been found to have been taken in New York, not Miami.
The original plan had been for The Beatles to stay at the Deauville for 84 hours (Miami Herald, 14.2.64) but the group decided to extend their stay in Miami to February 21st. They spent a couple of days water-skiing off Star Island (Paul had learned how to water-ski while on holiday in Corfu). They were sneaked out of the hotel in large laundry carts and visited the home of Mr and Mrs Malachi Garvey (Mal died in 2010). They had previously spent time on the boat of Bernard Castro.
