As far as airfare goes, i’m normally pretty good at finding a cheap deals. You just can’t be too picky. That may mean flying budget airlines (keep baggage and seating fees in mind when booking). Lately I have really only been using Skyscanner to search for airfare. I love how it shows you the cheapest options because you can compare days. Google Flights also does this. If you aren’t too strict on the days you travel you can always get a good deal. Another great thing about Skyscanner is that if you don’t care where you go, you can just search anywhere, anytime. Then if will show you all of the cheapest places. This is how I found my roundtrip flights to London for $350 and my roundtrip flights to Las Vegas for $70. I usually book pretty far in advance just because I get anxious. Be sure to put your browser on private. I am constantly scouring travel sites just because I think it’s fun. I think that’s a good way to find cheap flights. Check often.
I almost always stay in hotels/motels or camp. A lot of people use Airbnb, which I personally don’t like. I feel like if you are traveling with more than one person Airbnb or hostels just end up being more expensive than hotels because they often charge per person. Hotels are a flat rate, so you can split the price. Additionally Airbnb has a bunch of fees added on that hotels don’t have. If you are into staying in somebody’s house Airbnb may be a good bet for you, it’s just not for me. I normally try to book my hotels through Hotels.com because they have a lot of sales and a rewards program. When you book 10 stays you get the next night free. I’ve actually gotten many free nights from that site. I also check other comparative price sites and only book through Hotels.com when it is cheaper or only a bit more. They also have Cyber Monday deals. If you are road tripping camping is a super cheap option. I will normally just treat the campground like a hotel and still eat out or something rather than bringing a bunch of cookies supplies. However, I normally bring a french press to save on coffee. Private campground are normally nicer than State and National but very often cost more. State and National Parks usually have more exciting things to do. Sometimes you have to pay to reserve a site but it’s almost always the cheapest option.
