This is very true at the moment as no one is finding it very easy to get around. There are other means and they are a lot better than you may first think.
Just saving up for a bit longer could be the answer, the dream holiday can wait another 6 months. It becomes less annoying if you are on your way to somewhere like Disney World. I for one was saving to head off to Islands of Adventure when Harry Potter opens next year but now am forced to wait a bit longer to wait for Disney to do their magic on Fantasyland.
You could always go to somewhere that is a bit closer to home. Perhaps going a couple of states across or (if living in the UK) head to Dorset or Cornwall to experience the countryside and think about staying in a nice cottage for a few days. These short breaks can really do wonders for stress and your health in general so holding off that extra year does not always need to happen.
It is certainly not just the cost of flying and staying in a hotel or villa that gets people bogged down when it comes to going away. The prices of buying new summer gear, sun tan lotion, new cases, books and everything you need for your holiday soon add up so be careful and plan ahead. Another stressful thing is the airport, all of the security there can be very overwhelming indeed.
Once you are there (as long as you do not worry about the journey home) you are fine and can enjoy the nice weather and pool. For more tips why not visit a travel blog.
