Nope, lucky again I guess. Portland, OR is great to visit and most of the main attractions are free or cheap. The others I buy membership to anyways, so it's not a problem. The only $$ we end up out is for dining out.
Never thought about living near a major amusement park attraction, I'll bet it does cost you a bundle everytime guests visit. Actually, two questions, Why do you all have to go? And if they want you to go with, why are they not offering to pay? If you're feeling flush you could always say no thanks and pay for yourself, otherwise, it's a shame you have to spend big $$ to go see an attraction just to be with your guests...
