The Lightning Thief
Percy, Annabeth, and Grover went in there on their first quest in The Lightning Thief, and did not know that they were in there for five days, when it seemed like only a couple of hours. Percy realized something was wrong when he noticed kids dressed strangely, and found out they had been in there for years without even realizing it. For example, one boy had been in there playing games since the 1970s. Percy then shook Annabeth and Grover from their trances and they escaped.

The Lightning Thief (film)
In the film, instead of them just wanting to be at Lotus Hotel and Casino, Grover, Annabeth, and Percy had to get the last of Persephone's Pearls. Once they had gotten in, a waitress gave them a Lotus Flower it gave the effect of them never wanting to leave, which resulted in high-like symptoms. They forgot why they were there and decided to stay and have fun. Finally, Percy realized what was going on when he saw a person dressed in 70s style chlothes playing a game about a movie from 1971,  didn't know what a DVD was, and said this was the best game of the year. He got the others to stop eating the Lotus Flowers and come back from their trance. On the way out, they grabbed the third pearl and stole a black Maserati which was up for contest, crashed through the front door and escaped.

The Titan's Curse
Bianca di Angelo and her brother Nico di Angelo are mentioned to have been to the Lotus Hotel and Casino before. They entered the hotel in the 1940s and stayed for several decades. Then, the Fury Alecto, or Mrs. Dodds, came and got them out and sent them off to school. Because Hades had them dipped in the river Lethe, Bianca and Nico cannot remember anything before their stay.
