I haven't dived there so perhaps someone else can answer that better than I, however I would expect they would have some DIN tanks. I have dived Bali, Thailand, Truk, PNG, Borneo, Fiji, Tonga and all have had DIN tanks. The cost to rent is the same. You just have to usually let them know before you get there, or if there when you first get to LDS so they know you need DIN and that they take DIN on the boat with them for your second dive.
Now days tanks are usually made to take both DIN and Yoke. Its a DIN valve with an insert to make it usable for yoke. If you are concerned at all you can buy a DIN to yoke converter, then there is no tank you cannot use. If you look on the side of your DIN regulator, you will probably find it is a 300 BAR reg so will fit 300 BAR DIN tanks, 232 BAR DIN tanks and also (with a converter) 232/207 BAR Yoke tanks.
