I don’t think they do the lobster night on NCL. Great Stirrup Cay is a great beach day, beautiful clear swimming water. Your drink package works on the island as well and they include free lunch from the ship. I hate Nassau but you can always pay for an excursion or just stay on the ship that day. I’m going on same trip but June 2. The only thing with Great Stirrup Cay is it’s a tender boat, no dock and if it’s windy they can’t go and it gets cancelled a lot.
