Before you worry about your accommodation in Qatar, I should ask you, did you check what kind of visa will you need to get into the country? If you are not on a business or resident visa, are you going to be on tourist/temp visa?

Wouldn't that mean that your partner should get into the country first then invite you?

It is not easy for a woman to come into the country (unattended!!!) so, please make sure to check the visa process first.

Very good luck.
