On the Oasis class ships yes the pins get treated better. On the Allure the first lunch on ci, we had to wait while the pins got served, after waiting a long time I was served raw salmon.
I feel it is like entering an established club were every one knows each other and you are the out sider. Not a welcoming experienced.
Also vacations are precious to us since time off is hard to get, while pins this is a lifestyle. We are interested in the cruise experience while for the pins it is a social event.This changes the experience
