I called and got it done. Actually the girl I spoke to said by buying the two more excursions the rest would be discounted. So I did that but only $400 was then due to AE so i added $400 on board credit to make the $800. The excursions have posted but not the onboard credit. Perhaps this will take a while longer, maybe until Th credit charge goes from pending to charged. Anyone bought on board credit who might know how long it takes to post?
