Where to go on spring vacation?

I dreamed of going to Phuket. I plan to go there in March. I found an interesting article about Phuket www.iflyfirstclass.com/blog/first-class-flights-to-phuket . I think this is the perfect place to relax in the spring. The only thing that confuses me is the long flight. I don't like flying. But my husband said that in the first class I will not notice at all how the flight will pass. I really hope for it. But I'm so looking forward to this trip, that I will not be able to prevent or spoil the mood!
