OOC:
I was going to say just the two days, but, maybe not.
If he is the only one who is thinking of taking that time, he won't. He'll do the two days and notes. However, if others are going to stay the whole week, too, he'll do so. That way he can get things down as well as possible, since the cost of mistakes can be pretty bad.
Regardless of two days or one week, he'll still take notes, but he will memorize as much as he can using the tools they are lending him. He will also take notes on how to transfer as much of the practice as possible to his set of dice.
Follow-up:
Skeeve still wants to go back to the Highland Valley at some point because he said he would. He wants to help the village out with their night terrors problem.
On the other hand, he is curious about the lost city they are in the middle of, so checking it out is cool, too.
Regardless, he wants to continue to adventure with Blornvid and Ealdwig. So he's more than willing to compromise to get the group together.
