Sorry to hear your trip wasn't as productive as you'd hoped. In spite of everything, Mexico is still a wonderful place with excellent resorts. We've stayed in a couple of them, and there are definitely good reports here by past brides. But it definitely depends on what you want and don't want.
There is always Jamaica but you'll find your price points are different compared to Mexico. We had a wonderful wedding in Jamaica 4 years ago and loved it. I work with a girl that got married last November and did Sandals for her wedding in Negril. She's a bit over the top but her wedding cost her $40,000. I just about fainted when she told me. Her photographer alone was nearly $6,000 (Toronto one and she paid for his trip too). I still think you can do a wedding in Jamaica for fairly reasonable, again depending on what you want, so it might be worth a look.
