Hi @iMan
Your domain is not bad
You've got Hotels and the less important Planet + .com
It's difficult to give exact price but I would say 150$ in the best case.
The potential comes from the hotels that can be used for the hotel and tourist sector.
The problem comes with the planet... Ii you had a multi planetary hotel chain that would be a gold domain to have... Sadly, we still live on one planet still, so the potential is very small.
