The last I read on the CC board was that for standard cabins, it was 1 reservation for each specialty restaurant. Suites can reserve more (I believe it was twice at each). Nevertheless, many people commented that since the menu didn't change much, once was usually enough for the specialty restaurants.

Haven't sailed Oceania yet (was hoping to do so ;) ) but my biggest annoyance before sailing them is the soft drink/bottled water policy. Oddly enough (or maybe not so odd to some others as well), this is my biggest hang up with this line. Given the premium over mainstream lines, this is one area where they should look at including in the cruise fare, IMHO. I can deal with paying for my own alcoholic beverages - but given how cheap soda and bottled water are, this seems a little silly.
