Well the stars affect HMMFOMT and HMAWL, by what products are avablie to sell in both
games and also new events happen and "gossip"...and once you have your first succesful
link connection between both games, Van will appear in HMMFOMT and you will have new
products avablie to buy in HMAWL, also you can multiple your linky stars by each time that
you have a succesful link, and the door in the Inn is just a section of the Inn where Ann
and Doug sleep, not much, but if its open its a sign you gained there friendship though.

if you have all connectivity stars you unlock the seaside cottage, its pretty shabby
inside(wel it doesn't look comfy).
