Phuket Airpark, short 500m grass runway

Unfortunately the flight to Bali, originally planned for the last week of July, has been postponed to August and I have already arranged all my holiday and travels and cannot change again.  So what to do?  I decided I will fly into Thailand.  Maybe it is too late to apply for the permission to fly into Thai airspace, but I will try anyway.  The plan is to fly from Singapore to Penang and from Penang to Phuket.  On Phuket I am asking the Phuket Airpark to help me with the logistics.  I hope there is Avgas available at Phuket airport and the Airpark owners let me park my plane for a night or two.  Depending on weather, I may stop over on Langkawi and in Ipoh on my way back.  ETD Singapore is Saturday, 27 July and return on 31 July or 1 August.  Maybe other pilots who also took a couple of days off for the Bali flight want to join?  Please let me know.
