Hello fellow cruisers!

I am new the to site, and will be cruising in 4 days on the Allure! I am from Maryland (originally from Buffalo!). Has anyone had any successful get together's from the site on cruises? I've made friends while on a cruise before (in my younger years).  My boyfriend is not super social and wondering how to best break through that and have him enjoy fully the cruise experience and meeting cool peeps!
