First, there are small grammatical issues with their website that could indicate it might have been built by someone whose native language isn't English. 

Nicholas,The one piece of advice I would give is refinance the Condo before you start renting it out. 

If you really want to dig deep, pretend to be a renter and schedule a walk-through.

It’s all about catching their eye and making them click.

And then the personal page host is listed as co-host.

My Question is, for these up sales how do you expose these packages to the guests, are they included in your listing or added to the base price, if a guest chooses a package do they pay for the reservation how they would normally through the booking platform then pay for the package separately?

If you want to shoot me a DM on here, I'm happy to run your properties through the system for you. 

Unless you wait for the next tech/ICO bubble, during which you could sell anything.
