I would acclimate without the wetsuit, but wear two thick caps and ear plugs to keep head warm. My prep is more time that it is distance, generally spend 2 hours continuous swimming in the conditions I'm expecting to compete. I may hydrate after two hours, but little to no solid food. If you wear a wetsuit, you will probably need to hydrate more often since you will be sweating much more in the suit.
Good luck and enjoy those crystal clear, blue waters.
I will use lanolin for my neck. Have you used it ? doesn't matter how long you swim. At the end you have to clean it up with a towel from the neck. It is sold in Pharmacies at least here in Spain.
I prefer to use the wetsuit. I am a warm water fish, 18º is cold for me used to swim in the mediterranean. I know for you guys in the Pacific , it's different.
Thank you for your tips.
