The Valentine weekend is this year celebrated with the Chinese New Year in Thailand and it is a perfect time to just enjoy yourselves.
Book a hotel with a spa package and just enjoy the many wonders that Thailand have to offer in from of spas and massages places.
You will find some of the best offers on the English speaking magazines in Thailand and some on Google as well. Be sure to book the hotel or spa in time because the weekend of Valentine this year will be crazy.
I think you should be lucky enough to find you find a hotel that is not fully booked yet, close to the beach book it now. But if you do not have time for a long weekend just book one of the five stars hotels in Bangkok near the river and a have some magical moments.
If you want to top your spa weekend with some lovely flowers we suggest these two florists
