After flying into the Cancun airport, you will take a private van to the ferry dock. Once you board the ferry, it is a stunning (and quick!) 15 minute ride to the island. Once you get on the island, you can either hop in a taxi at the taxi stand outside, or simply walk to your hotel if it is nearby.
US dollars are widely accepted across the island, however to ensure that you get the best exchange rate, we recommend paying in pesos when possible. Once you exit the ferry, there is an ATM directly across the street, as well as a cash exchange booth (there are many other ATM´s throughout the island though). Be sure to notify your bank that you are traveling to Mexico so that you don't have any issues using your debit/credit cards while in Mexico.
The short answer is no- but there is more info to be shared. The water is purified, but it is extremely hard. All hotels and restaurants will provide you with filtered water and ice- no one will serve you tap water (even if it is in a glass and not a bottle). It is safe to rinse your produce in the water, and perfectly fine to brush your teeth with the tap water. But as a general rule of thumb- only drink bottled water.
Yes! The media paints a very different picture of Mexico than what is happening there. Like all countries in the world, there are parts of Mexico that have problems, and there are parts of Mexico that are incredibly wonderful and safe. We happen to be in one of those great places. We recommend that when traveling (anywhere in the world) you keep an eye on your belongings. The majority of crimes that happen here are crimes of opportunity- you leave your iPhone on the dash of your golf cart, and someone will walk away with it. Apart from that, which can be avoided with just a little common sense, Isla is a really safe and easy island to explore, and we encourage you to get out and see it.
Located mid island is an awesome grocery store called Chedraui. This store is basically a mini Wal-Mart. They carry everything from clothes, swimsuits, TV´s, medicine, toys, alcohol, home goods and food/produce. You can find almost anything you need there. If it is more of a specialty item, don't forget that Cancun is only a ferry ride away. Located in Cancun are US style malls, Costco, Sam´s Club and more.
Whatever you would put on to go out to a nice dinner is perfectly fine for the wedding. Remember that the island is in a tropical climate, and that the weather can change from day to day, but generally- it is hot. Light weight linen shirts, linen pants, and light weight flowy dresses are perfect go-to´s. Nice sandals or easy to slip on shoes will work well in the sand.
