Hi Rebecca
Welcome along!
Yes most, if not all nylon string guitars have wide necks but are perhaps easier on the finger tips than steel strings.
Obviously steel string guitars will come with narrower necks than the nylons, but I guess you have to weigh up the stretching that you'll have on the nylon string guitars
verses the finger-tip pain that you will have with the steel string guitars.
Although having said that, the pain you'll get on your finger tips will go in time after your fingertips harden and form callouses. I hope this hasn't put you off, but don't fear 'cause I'm sure that someone in the know may have more helpful advice for you.
So stick around!
