Never be mean even to yourself. There is no sense in saving all you have in the bank. The bank will be making huge profits from investing your money. I am not saying that you should never save. Saving is good if done wisely. You can spend part of your savings on a trip to the Oregon campground that you wish to have your vacation from. This will be a wise spending of your money.
Look for the best rates that are available on the Oregon coast hotels. Take advantage of any discounts that come when you make you early reservation bookings. Again, it is not wise to spend on a vacation blindly. At all times try to minimize your budget so that it does not leave your account at 0 balance.
I believe that if you begin early enough to look for the Oregon coast vacation rentals that are available, you may compare prices and eventually you will manage to have what you need. You will find a spacious rental that is in a convenient location and safe. It will also fit into your budget well.
As much as Oregon camping is a need, there is so much in terms of discretion that it requires. Check how you spend. Do not behave like your life is stopping at the end of the vacation. There are other things you may need to do with the money you will have saved.
