Call your major credit card company and inform them of the dates and location of your travel plans. This limits the chance of having any issues when trying to use your credit card when you are on vacation. Have a happy and safe trip.
SAND FLEA BITES: I have not found an effective repellent, BUT I do strongly suggest you take a small bottle of Calamine Lotion with you. Dab the flea bites with Calamine Lotion to relieve the itchiness, and prevents the bites from blistering. Re-apply regularly. It really helps!!
