Ive been to both and I HIGHLY recommend you stay at the Iberostar (IBC) instead. The Sun Village resort is further away from the POP airport and nowhere near as nice as IBC as far as decor, ameneties, food and ambience. Once you stay at IBC you will not want to go anywhere else trust me. I try other resorts and always regret it and end up booking back at IBC!!!! IBC has great a la carte restaurants, a beautiful pool with a swim-up jacuzzi, beautiful rooms and great customer service. EMI Sun village is much larger resort and the rooms are so far away from the main lobby and restaurants that you feel like you are walking miles before you get from one place to the other, there is not much ambience here and the decor and food leave a lot to be desired. I hope this has been helpful, let me know what you decide. Good luck
