Decorating for the seasons question

@starlitskie Hello!  I totally understand wanting to save some time there but, as daunting as it may be, I suggest decorating for each season separately.  I've noticed some inconsistency with existing decorations "counting" toward the holiday goals.  For example, if I leave my "Halloween" decorations up, sometimes they count toward the "harvestfest" holiday.  However, not all sims in the household will get the decorations completion and I end up having to change some things while those sims are active.  In general, I've noticed that if I just wait and decorate for each holiday separately, all sims in the household will get credit for the decorations. 

I haven't tried saving a lot with specific decorations for each holiday, so I don't know if your plan will work but I wonder if you may run into issues with having enough household funds to load a new lot for every holiday. 

Overall, I find it rather rewarding to choose specific decorations for each holiday.  Personally, I very much like choosing specific decorations for Halloween and Winterfest.  As for other lots in your game that you would like to decorate but aren't actively playing, the game will automatically decorate unplayed lots based on the settings for the holidays.  Hope this helps.
