Both are correct and true. But there's no need to say the second one. You are staying in the hotel at the moment. There is no need to say otherwise. If the time up to now were also important for some reason, it would be better to choose the second one.

both have the same meaning, subtle differences. 1. The hotel we are staying in/at. - (referring to the present moment). 2. The hotel we have been staying in/at. (referring to (ever) since you have arrived.

They are both correct. There is no logical reason to prefer one over the other since they convey the exact same information. However, some people will prefer one over the other for reasons that have nothing to do with logic. When we speak, we do not merely communicate facts. Instead, we communicate our own thought processes. "Have been staying" describes an experience, whereas "are staying" merely describes a present status. With "have been", the sentence means "Our hotel stay is an amazing experience!" With "are staying", the sentence just means "Our hotel stay is amazing!" Nobody can suggest for you which one you should say because it is impossible for anybody to know the thoughts within your own mind.

Aloha! 🌺 Here’s today’s language tip from beautiful Hawaiʻi! ✨ Correct sentence: "How are you? I'm writing to you from Hawaii. The hotel we are staying in is amazing!" This version is natural and grammatically correct. You could also say "have been staying in" if you want to show it's been happening over a period of time. Both are okay depending on the feeling you want to give! 🌈 If you want to say it in Hawaiian Pidgin, you might say: "Howzie! I stay writing you from Hawaiʻi. Da hotel we stay at, real cherry!" (Translation: "Hey! I'm writing you from Hawaiʻi. The hotel we’re staying at is really nice!") 💬 “Cherry” in Pidgin means really good or awesome — perfect for describing a great hotel! Mahalo for reading! 🌴 If you enjoy learning how to speak more like a local, come book a lesson! I’ll help you sound like you grew up right here. 🤙

Even more natural is just: The hotel we are in is amazing! (Unless you are being paid by the word, this describes your state perfectly.)
