To give a full understanding of my question, I'll give some short background info.
I'm working on an Easter Island website where I offer travel tips of all sorts, a travel guide, tours and hotels. I'm working on the description of the site that appears when you search in Google (maximum 115 characters).
I'm looking for a word that describes a place or resource where you can find everything. This is what I have now:
Welcome to your ultimate metropolis for Easter Island tourism! Plan your trip and book the best hotels and tours with us.
It seems I can't use metropolis in English, right? I'm from Sweden, and in Swedish you can, but it seems you can't use this word in English like this, right? Any ideas of another word? Or any ideas of re-phrasing the description? Thank you!
