When we first started with NCL, not including the Norway, we were very hesitant about Freestyle. We were used to traditional cruising. Someone I worked with tried to sell me on the idea of Freestyle, but we resisted. Once we finally tried it, we loved it. Time on board is your time. Food is always available in a variety of ways. There are plenty of activities, you just have to read the daily paper you get in your cabin each evening.
The only downside, is, even though it can be inexpensive to get on board, they tend to nickel and dime you ( but all ships seem to do that now ). There can be a lot of pressure to buy photos, eat in the upcharge restaurants, buy shirts, etc. But you don’t have to buy these things. Just resist. However, I do recommend Cagney’s Steakhouse and Le Bistro ( French cuisine ). For some fun, eat at Teppanyaki ( hibachi style dining ).
Another reason we love Norwegian, is they sail year round from NY, and even though we could sail with Royal Caribbean out of New Jersey, they tend to be a higher price point, with huge ships that don’t appeal to us. We may book with them in the future, if that’s the way our friends want to do it, but we receive Platinum perks with NCL, so we really don’t see the need to switch.
