I live in Bangkok, and have stayed often at Hyatt. i love it, the regency floor is great. But if you are Hilton Gold, the Conrad executive floor is wonderful too. I live in a serviced apartment, on wireless road, that is a 5 starr hotel, that might be your best bet yet. All are equal in location, and amenities, price is close to same. I suppose i would vote Hyatt cause i love them hyatt points. But conrad might be the best deal, most for the money
