Since I made modifications to the ship design I received, I created new instructions. I added some icebergs for Alaska. I used the Bricklink Studio software to create the instructions. They look just like the ones that come with
Lego kits. I also wanted to personalize the instructions for my cruise. I then ordered parts from Lego using their Pick-a-Brick option. Some pieces will come in within a week or so, but others can take about 2 months. Be sure to order with plenty of time and immediately check the order when it arrives. Some of my pieces were missing, but Lego sent new ones for free. It’s bound to happen when you order 100+ of a specific tiny piece.
