While I do agree times are not as great as they could be, I do not believe it is still economically as tough as it has been either. In fact, I believe the economy is going up, while it is still not doing too great, it is still pressing upward. With that said, I still do not think that it always has to be a choice of one or the other and for me at least, I get the vibe that many people view it as that, even if they can afford both. I look at myself as an example, honestly I can not buy both passes. I should be saving as much as I can; however, I still buy useless things everyday that I do not need and can live without. It is my belief many people buy useless things every day that they do not need and can live without happily, like going to a fast food restaurant for example. When it comes down to it, each park offers pass that, would equal up to $46 per month (a Platinum Pass at each). I can think of $50 I have spent that I could have put towards those passes instead.
Keep in mind, I am only referring to single adults/couples. Not families, I do believe for a family it can be rough. Essentially looking at prices with it being about $50 per person, a family of four could end up paying $200 for Platinum Passes at both parks.
