This is something you need to discuss with your provider ahead of time. In my experience, alone time is essential for both during any meeting longer than an overnight. I usually schedule 2-3 hours a day of along time but again, this should be discussed and agreed upon in advance. While I don´t really care too much about a provider using his cel to reply to messages and quick checks, some really can put their phones down. I think that discussing and agreeing in advance each others expectations goes a long way for having a great experience.
