I think I figured out the way that Oceania handles the $800 excursion allowance (or any higher amount). This is under the new "Simply More" booking procedure. You can go ahead and book excursions well before your sailing and when you look at an excursion, it will show 2 prices. One is the regular price and the other is a 25% discount price. When you book, then Oceania will automatically charge you the higher price. THEN, once you get to 4 excursions, the computer should charge you the lower price for each excursion. The game they are playing is "let's give the *****, $800 excursion credits and make it mandatory to select at least 4 excursions". The hope is you will go way over $800, even with the lower price and then you will owe money!!!!
