I was at an ATM, and picked up one of the freebie magazines which detailed a leisure route around Hua Hin. Most of the route was fairly standard - places I had walked dozens of times, but the following 2 entries caught my eye:
Go furthermore to very end of the road; you will enter another symbolic place of Hua Hin- Sofitel Central Hotel (1st hotel built in Hua Hin), where its landscape is unique by formed tree. Take some time relax at the Museum Café in the beautiful colonial architecture. (Suggest walking in from the side and outing at the main entrance.)
Both entries appealed, and I tried to gain entry to the Sofitel - I went to the suggested entrance, only to be directed to the entrance on Naresdamri Road. At that entrance I was turned away, and told guests only. Despite my protests, and those of my wife (in Thai), we were not allowed in.Hilton hotel seems to be a Landmark for Hua Hin already since more than 10 years ago (nice viewpoint on the 17th floor).

As refusal resulted in embarassment

I am coming back to Hua Hin in April. Both entries still appeal (and the magazine is still advertising the walk - despite my complaints to the editor). I often see postings by people talking about eating at the big hotels. Is there any way that I can gain entry to either the Sofitel or Hilton without being arrested?
