I have been to the island of Isla before and stayed for 3 days. Love it and that is why I am going by on Sunday...YEAH!! I am taking my mom with me this time. She is a little concerned that she might get sick from the food in the different restaurants since we are staying at a condo and will eat out a lot. I told her I didn't get sick but is there any other advice I can give her?? Like some dos and don'ts as for food and drinks that might make her stomach a bit upset??
