Thanks for the heads up RedKettle
As a student of 'bush' craft, and a believer in healthy paranoia, I'd be grateful if you could explain the kind of scenario that could ensue 
You are announcing where and when you will be in a specific place (to anyone who knows that WG) which means if anyone is wondering whether it is you making your posts they have a good way to check that.
Less dramatically it means the WG has the ability to link your ID with your UKP ID. So for example even if you wait a few weeks before posting a negative review they will know it was you - which might not matter (especially if you have used punting phone etc etc).
Security is a personal matter, I do what I feel is appropriate for my circumstances, and I suspect many on here will think my comments are over the top. I am not saying you were wrong to post as you did - just for me I would be wary of flagging specific details in advance.
Hope that helps.
