Convention apprehension

Trying to decide if I should cancel Discworld and go to Nineworlds instead. Flight is booked. Have membership for Discworld.

Discworld:
Hassle to get to. Train ticket prices rocketed though.
Haven't booked a hotel. The overflow hotel is more expensive (for a single) and not as good.
Presumably someone will want my ticket. There's an easy mechanism to sell it.
I can probably get a lift which mitigates the first issue. Will need to arrange this.
I do rather like the costuming potential.
Don't get to see tinkerbell1980 and medium_jock very often. Or masterofapath and tictactoepony for that matter.

Nineworlds:
Is very convenient to get to. I can get a free bus from the airport, or a taxi is affordable. Coach from airport to Brighton
Really loved the last one! It was so much fresher than more established cons!
Hotel has space.
Works out a lot cheaper.
Will be awesome people there as well.

So I'm quite clearly biased towards changing my mind really my inclination is to change my mind. The only reason I really want to go is because there are friends I don't see a lot of going. But that is a big factor.

Wondering if there's anythng I've failed to consider. Wish I was more decisive.
