The defendant was detained after eight minors and one adult fell ill at the facility in mid-summer.
The senior citizen, from Ruddington in Nottinghamshire, pleaded guilty to a total of 17 charges when he was present at the judicial center on recently.
Nevertheless, he refused to admit a single sexual charge he was charged with, which was against a young boy.

'Treat game'
The legal representative, handling the case, described the criminal behavior to the legal proceedings.
She explained his targets were under-privileged children who were attending a youth camp which he ran.
The defendant conducted a "candy game" with the minors, Mrs Prior said, in which he would access the sleeping quarters when they were settling down and ask them to consume candy "as quickly as they can".
She informed the proceedings Ruben had played this game with the young males "repeatedly", and minors had earlier experienced illness the subsequent day.
She said the man had been capable of justifying this repeatedly as the youngsters being "overstimulated by activities", until his stepchild had suspicions in recently.
The prosecutor continued: "This year his family member had suspicions about what was going on, for good reason.
"They decided to have a look in the individual's items."
Mrs Prior KC explained objects including infant oil, ointment and syringes were located, and his family member alerted the law enforcement about his worries.
She explained Ruben continued to engage in the "candy game" with six boys that evening - July 26th - and they were all ill the subsequent day.
"Authorities" had not gone out by that stage," she added.
The regulatory agency, the investigative body, had stated that it was examining the police response of the incident.
The legal representative stated the children were unable to walk properly due to their sickness, so the stepson notified the authorities a second time.
She stated the man then conducted the "sweet game" in a room of five minors.
