Thanks for taking the time to look at my guide, this is the first one I've created! I will update with information as I learn it (or as you all may feel free to add in the comments if you'd like). This guide has the complete list of all 27 NPC/shops needed to complete the achievement with "general" locations as to where to find the shop itself. Seasonal Shops or Event NPCS do not count towards the achievement, therefore it may be completed anytime. There is no special action required to obtain the achievement, simply walk to each shop, Press "E" to talk to the NPC, open/close the shop window and move to next location. I tried to keep an organized path from one location to the next to keep the route short. Enjoy!

UPDATED DECEMBER 29 2022 ~ There is now 27 NPCS to collect!
Special THANKS to Drachy Gozen who took time out to give us some updates in the comments!

Sir Reel has two locations and only one needs to be visited to complete the achievement. I started with the Fishing Hut located right outside of the Poseidon Roller Coaster. Alternatively, he may be found at the dock behind the Games Hub building.

Franky's Grill is a hot dog stand located on the Boardwalk outside of Fresh and Celebrations and in front of the Poseidon roller coaster and the Ferris Wheel.

Horizon Condos is located inside of the shop Sweet Suite Furnishings which is one of the shops located at the base of the Tower. Note: The NPC randomizes between a few men and women you are not required to talk to each visually different NPC. Each "version" of NPC will result in opening the same shop and speaking with "Jeff".

Seasons is a greenhouse/garden located above the row of shops containing; Sweet Suite Furnishings, Rob's Imports and Central Circuit. It can be reached via stairs alongside Sweet Suite Furnishing or jetpack.

D.I.Y can be found in the Tower lobby facing the row of shops that contain; Sweet Suite Furnishings, Rob's Imports, and Central Circuit.

Folio can be found inside Tower Theater to the right or left side, allowing you too book private movie rooms.

Darien is one of the 2 NPCS inside of the Bowling Alley, standing behind the counter. The NPCS are 2 SEPARATE shops and it is required that you speak with BOTH to complete the achievement.

Although not technically a NPC the vending machines are considered a shop and one must be spoken to in order to complete this achievement. You are not required to speak to more than one. I chose to use the one inside of the Bowling Alley next to Pinhead and the Bowling Pro Shop. Alternatively, the vending machines can be located in the ; Arcade, Tower Theater, Hidden Dev HQ ( located via my other guide).

The Arcade is located right in the main plaza almost directly across from the Tower. Upon entering if you follow the path (left or right) to the main room of the arcade, you can spin around and see 3 NPCS and their respective shops. Volt is the character working at the prize counter.

Virgil T. Chad is 1 of 3 NPCS in the Arcade and works at Uncle Muscles Pizza to the left of the prize counter.

Chilly Billy is 1 of 3 NPCS in the Arcade and works at The Freezing Point to the lright of the prize counter.

Wade is 1 of 2 NPCS that can be found in Tower Unites nightclub, Volt. Volt can be found alongside the Arcade in the main plaza. Wade is located at the bar, on the ground floor ont he left side of the nightclub.
