All gone quiet??

Since my big win - I feel a little deflated - but I'm trying very hard not to be. Sales haven't risen dramatically, no famous producer has contacted me to beg for my book to be turned into a drama - I am still me, known by those who love and respect me and perhaps a few who don't, but at least I'm still here and still writing.
I may be naive where winning competitions are concerned but if you're a winner and invited to an award ceremony - shouldn't I be looked after?
I mean, should I pay for my ticket to go to an award ceremony that is giving me, among others an award for winning? or am I being egotistical?
I expected to pay for my hotel and flight but when I've paid to enter the competition, I wonder if i should then pay for everything else - ie, paying to be awarded essentially, which to me, feels wrong?
I would love to know what others think who have won awards or even from those who have an honest opinion on this.
