Hello Mille and a very warm welcome to the forum. Yes you are right we all love Arillas.
You will be pleased to hear that Arillas has plenty of local families who live and work in Arillas. It is these very families who give Arillas it's heart and soul making it such a special place for those who visit...and undoubtedly return.
I am sure as you read through the main website and this forum you will find plenty of information about Arillas, what to do, where to eat. where to go for a day out.
I cannot offer you any information on the Tropicana as I have never stayed there, but it won't be too long until another member pops in to tell you all about it.
You can see the location of the Tropicana on the following map. (you will see it is just a short stroll away from a lovely bakers shop!)
