A
Wouldn’t you want to travel more often without breaking the bank? If you are interested, read on to find out how you can do simple things to save money next time you go on vacation.
Airfares
Plan in advance and visit discount websites to see if there are better deals. If you are planning to stay in two countries and an airline makes you change planes on those countries anyway, you might be in luck. Check pricing on the flights to see if you can stay a few days at the country of the flight change instead of changing planes right away since airlines often let you do that for the same price.
Accommodations
Sometimes the smaller towns close to where you are going have hotels that are much less expensive. If you don’t mind the 15-minute ride, you might just save a large amount of money. Home exchanges are pretty cool and popular especially in Europe. If you are of the adventure type, this could be exciting and refreshing. Sometimes smaller hotel chains are willing to give you free upgrades or even free nights. If you are staying at a destination for at least a few days, consider a vacation home instead of hotels. They are often more comfortable and your cost will probably be cheaper.
Eating
Figure out where you will be and eat before you actually go out. Avoid breakfast from the hotels because chances are good that the breakfast from the hotel is expensive and isn’t great. It probably pays to walk out the front door in the morning and find a local cafe. You might just discover the local favorite unexpectedly. Want a breakfast that costs nothing? Ask for some bread to-go at the restaurant the night before. In addition, fancy lunches are often much less expensive than dinners. If you eat a big lunch and a light dinner, it’s also healthier.
