Two government workers from Washington D.C. have been arrested in Miami for trying to smuggle drugs on board an all-gay party cruise ship.

Peter Melendez, 35, and Robert Koehler, 27, were arrested on Sunday when they were boarding the Royal Caribbean's Allure of the Seas ship at Port Miami.

They were caught after a Homeland Security agent intercepted emails between the pair discussing how they could smuggle the drugs on board and sell them to fellow cruise-goers.

The emails were intercepted via Melendez's government-issued computer. 

Miami-Dade Police were notified by federal agents that Melendez and Koehler were going to board the ship with drugs. 

While they were waiting to board, a K-9 named Bill alerted police to the drugs in their luggage. 

Police found 27g of MDMA (known as ecstasy), 18g of Ketamine, 246g of GHB (known as the date-rape drug), Viagra and Adderall in their luggage. 

Melendez was arrested and charged with conspiracy to traffic in illegal drugs and trafficking in illegal drugs 

Koehler was charged with trafficking illegal drugs. 

They admitted to carrying the drugs when questioned by police, according to authorities. 

The sold out cruise ship set off on Sunday for a seven-day Atlantis party cruise, which promotes itself as being the world's largest all-gay cruise.  

It was making stops in the Bahamas, Mexico and Honduras. 

The Allure of the Seas ship can hold 5,400 passengers and has over 2,300 crew. 

The cruise was billed by Atlantis as, 'everything you've ever dreamed of and more fun than ever with our nonstop festival of spectacular performers, legendary DJ talent, outrageous parties, thrilling activities, and so much more.'

Prices for the week long extravaganza started at $849.
