So I tried to search through the thread about this, but it was either from long ago or did not include the ports I am looking at. In Costa Maya, the dolphin touch is a 10 minute walk from the ship, you can see it from this ship. If I book on my own it is about $50 cheaper overall. On their site it has info about coming from cruises, so it doesn't seem that they won't take a reservation for cruise passengers. Anyone do this? Did it work out for you? I know I take a chance of missing out if the weather is bad, but is that the only drawback?
