Thanks to all for that flood of responses.
Yes I've got the message I was expecting - it is down to the arbitrary discretion of the immigration officer!!
Anticipating problems - at Hong Kong - Ana Lyn had already been provided with & was carrying;
1. Letter from me
2. Photocopy of my passport
3. Copies of the reservation in here name at The Sheraton in Kowloon.
She also had registration for the Hong Kong Gift Fair.
Today I have now spent 3 hours at The Philippines Consulate in Hong Kong dealing with paperwork and standing in lines. I have to go back at between 15.00 & 16.00 to collect the affidavit. Another 20 quid wasted on top of nearly 100 on phone calls on Friday night plus yet another rapacious charge from Cebu Pacific.
I am not amused!!
& if the Philippines government has a lurker on these forums - as they should have. Guys you have a problem. In 2006/7 I invested a huge amount of money in The Philippines that resulted in well paid employment of over 100 people. I am in the process of making a decision for a similar investment in 2009 with a choice between Manila, China & North Wales. I was also thinking of setting up a business in Davao. This on top of the problems I have had with Philippines petty administration before means that my final decision is likely to be as arbitrary as that immigration officer's was at Davao on Friday night!!!
