Xiamen Ferry for foreigners

Hi just a question, I'm arriving tomorrow around 8pm and I have a hotel booked. I'm confused about
1/ the limited number of visitors. Will I be able to get there?
2/ where to take the ferry. I read on wikitravel that foreigners are not allowed on the ferry from lundu and need to get to another one which is elesewhere and more expensive
3/ if I can go from lundu, what time is the last ferry from Xiamen to gulangyu?
Thank you for your help
