If your invitation says "and Guest" then yes, if not we prefer it's just you.
We love kids, but to give all our guest the opportunity to let their hair down and have a good time without having to worry about little eyes and ears, we politely request no children.
You are more than welcome to stay where ever you would like to. However there is a fee of $150 per person to come to the hotel for the wedding that you will pay for at the front desk when you arrive. You can only show up 30 minutes to 1 hour before the ceremony and stay until the end of the reception!
As of right now, you will NOT need to get tested to enter Mexico. You will need to get a Covid-19 test to enter back into the United States. If you are NOT vaccinated you will need a test 24 hours before your flight. If you ARE vaccinated you will be required to show proof of vaccination and a Covid-19 test 72 hours before your flight. If you are staying at Hyatt Ziva, they will schedule your test for you. It is done on the property and at no charge. Check with your airline to make sure you have the appropriate test that they require. For more information visit: https://mx.usembassy.gov/covid-19-information-for-u-s-citizens-in-mexico/
