I've had it done - with quite a lot of my soft palate taken as well as my tonsils.
It is pretty sore for a week or so - oddly enough in the ears more than anywhere else.
The result is, I can swallow horse pills because they don;t touch the sides, and I have to be careful because food and liquid are more prone to 'slip down the wrong way', but you get used to that surprisingly quickly.
Hopefully it will sort your snoring - I had mine done for aponea which included snoring as well.
To sum up, it's unpleasant surgery, but the effects wear off fairly quiickly.
My advice - get a large box of soluble Solpadene, and take them every two hours to keep the pain-killing on a constant level. Have them with a glass of water my your bed, and when you wake in the night - and you will - have them straight away.
Good luck.
