Re: Cancun
I went to Cancun 2 or 3 years ago. It's a lot of fun, great for couples and even families. There is definitely a lot to do there from seeing the Mayan Riviera and ruins and going to the amazing Xcaret park where you can swim with all sorts of fishes. You can also go snorkelling or visit Cozumel which is close to Cancun. I went snorkelling here and it was amazing. Be sure to visit Dolphin Beach, if you are staying a hotel where that gorgeous blue water is ... it's a short bus trip. Yeah, we took local transit. It was fun. :)
