It's not hard, people just aren't utilizing what the game is giving them to use. This just further shows how much modernizing and dumbing down games has affected the casual audience in not wanting to use their brain.
Charm scrolls, staves or spells make it so you can still talk to NPCs and use shops even if they dislike you being a vamp.
The sun damage is the only downside besides fire weakness, but that's why you get fire resist spells, pots or scrolls. The sun damage at max stage vampirism is easily countered if you use a good healing spell, otherwise just stay indoors and wait till night to travel. Not a problem at all.
