[X] [Alicent] A Trip To Dragonstone
[X] [Steffon] Urge Him to Seek Some Other Role in King's Landing
[X] [Marriage] Speak to Viserys
A visit to Dragonstone is sensible even if it were not for a romantic getaway. Taking the boat can be explained as us bringing our own staff to the castle to properly establish our demesne.
Steffon is not qualified for the guard, he will last as long as it takes for one of his subordinates to get sick of not getting his bribes and will fall out of a window on top of 50 knives.
Viserys has the main say in the marriage as our liege and father. For all that I favour the Dornish match we need to know more about him and Viserys is the only one that could arrange a proper face to face meeting for us to get a proper feel for him. Letters can be deceptive and intercepted preventing either of us from being truthful.
