I think that if someone enjoys the existence of crypto and would like it to prevail that they should support companies that use it as a payment method. Personally think crypto is inevitable despite various government, banking, and media entities doing all they can to the contrary. There are a few options out there for travel bookings but on that really stands out to me is Travala.

I don't personally use Travala exclusively because they don't as of yet have as many options as other more established websites out there for hotels and flights but they do have enough, and very similar prices for all major destinations. In many instances I have found that Travala is cheaper than other competitors like Expedia - which only accepts credit cards as far as I know.

I know that every company says this and that it is probably pretty difficult to cash it in if you were to find an actual lower price, but this guarantee isn't completely meaningless. I've never had to attempt to cash it in when I use Travala because when I do compare prices between sites, they are so similar or exactly the same that it would be a waste of time for the $1 or so difference that you might discover.
The main benefit of Travala is that it is one of the only established booking sites that accepts all manner of crypto as payment.

They accept a great many more cryptocurrencies as well and of course you can pay by credit card if you insist. You can see all of their myriad of options by going HERE.
It is important to note that Tron is one of the cryptos that they accept.
Even if you don't want to pay with crypto and this is something that has occurred to me in the past because I don't necessarily want to book something that has my real name and passport number on it for fear of government agencies asking too many questions, you could still use the site and pay with a credit card that you were going to use anyway, just to support the cause. The price is going to end up being the same anyway, so why not?
I strongly encourage everyone to at least have a look at Travala.com because they have been working so hard to make crypto something that you can use to buy things that you are going to purchase anyway, and at the same price.
