second floor was to be constructed for the IMAX theater, meaning that of the 14 halls it has always had since 1996, two had to be merged to meet the standards of an IMAX theater to accommodate up to 400 people. Another renovation to the Montehiedra location is the first 4DX theater hall in Puerto Rico with synchronized motion seats, and special effects such as strobe lightning, mists, wind and bubbles. In May 2016, Caribbean Cinemas announced that AT&T and Toyota would be the corporate sponsors to the IMAX and 4DX theaters, respectively, upon their opening at Montehiedra Cinemas. It reopened in June 2016 debuting the first IMAX and 4DX halls in Puerto Rico. The Caribbean Cinemas theater at Plaza Carolina also underwent renovations to make way for the second theater of the chain to have 4DX and IMAX, announced in August 2018, and opened in November that same year.
