I NEVER give out that info.....Lots of reasons they are asking and not necessarily positive...always better to be low key in Jam...dont tell your coming/goings and for goodness sake dont be giving out your phone number# to people you've just met or only know for a few days/weeks..etc..Take there # if you think you need it...( i've seen/heard this done by many visitors-many with negative consequences in the end)
I mean serious, why do they need to know this info or why do they care where your staying and when your leaving???
