I have a Credit card Ecertificate and have tried to book Grenada. Same message your E-cert not available for requested stay. When I pull up alternative dates it showed no availability on any date. Customer service said problem was with hotels system. Contacted hotel, after much trying they said problem is with Customer service. Have played with booking several places in US, no problem. Tried several out of country, all do not work with same message of Grenada. Again, this is not a freefri cert but the Credit card annual E-cert which is suppose to be able to use anywhere. Anyone else able touse theirs out of country?
