We have 2 islands, also Pear Island in Northern Hemisphere, we have 4 players on each and on Nookadoon we created a throwaway player (Jack) to be the island Rep. We moved the 4 players to the other island until Jack started Nookadoon, then moved the players with their houses etc to Nookadoon. We did it twice, tried keeping the villagers in tents, used teraforming to create fake bridges - both times after a few days the villagers got houses. Once the villagers got houses we developed the island and filled the museum etc. Yes it involved time travel and setting the clock to 4:58 AM and restarting the day to build bridges etc faster. We Also used amiibo cards to get winter themed villagers.
Update:
We finished the museum on Shell Isle (island after Nookadoon) and restarted it again as Cool Isle, we still need a tuna to finish the museum. I learned I like it best the first few days when the player does not have one bell to rub against another. However, time moves on and after you get so far it is better to finish it out. Setting the clock to 4:59 am allows you to restart the same day, I did not feel like waiting 2 days for Residential services to upgrade so I used that method to speed it up. Isabelle said we were level 2 and needed more residents. I used the 4:59 am trick to add villagers, after I thought we added the 8th villager Tom Nook said I could not add any more. I figured I screwed it up because I did not talk to Isabelle enough. Prior to adding more villagers She told us we were at level 2 and needed more residents. Anyhow, when I asked she said we were level 5 , a couple hours to go from 2 to 5. We are not creative, so our islands have the basics to be level 5 . We usually use 2 players with nothing to get to level 3, then move our regular players in with their houses. However this time went differently so our regular players came back after reaching level 5.
On our sister Island, my wife’s player house has passed 300 thousand score with Happy Home, I thought that was pretty good. She likes to collect photos, I think she has 60+ different villager photos. After she gets their photo she gets rid of them.
However, my favorite scene was Tom Nook shivering one cold morning as he gave the speech. Next time I will make a video.
