Mortal, saving the game doesn't save the characters at the inn; only entering and leaving the inn saves the characters that entered/left.
Even with the patch there are a number of quests that will keep giving Xp every time you enter the guild. What I meant is that when you recieve the reward for a quest, and quickly toggle between the different members of your party that are members of that guild, they will recieve the Xp and guild promotion every time they are selected. But that doesn't work with the patch.
By the way, I think it's a very good idea to order a number of the tips for starters; I just wanted to add a bit to it.
