Couple of questions from a relative newbie

Hi guys,

Been playing since the start of December and just hit level 60. I have a couple of questions I was hoping you could help with:-

1. In scenario's, does the money and tickets I spend come from my actual budget? If so, it warns at the start that cards received from the research centre aren't transferable to my other parks. So is it worth it? Can someone explain the benefits?

2. My second question is a bit more general. I started playing a couple of days before the Christmas season started. What happens to the rides and decorations purchased? Do they change to more generic versions? It would seem weird to have a big expensive Christmas rides/decorations/snowmen walking about until mid August or something.

Thanks folks.
