Today, I just a searched another platform which is giving the same service like goeureka even they are giving flight and car rental service as well, and best part is that is also in crypto. seems crypto will be the next way to make all payments.
I have also did the research and i found some similar projects like goeureka but would like to tell you that many of them are giving these services but no one is givin the features like goeureka because goeureka is only focusing on hotel booking sector and they are trying to make this platform very beautifu. I also recommend this way to explore your project because when you focused on multi sides it becomes harder to run and understand, according to me goeureka is doing the right that first they are settling down their hotel booking patform. after that they can climb to next step.
But i think they need to hire the good number of resources to do all these things which others are doing because i dont think its too hard to work on different parts of any project, but hope so they will launch all these things very soon.
