Visit visa for family members is one month renewable for a maximum period of five months for immediate relatives and two months for other relatives and is 220 riyals. There are no special conditions for it.

Tourist visa is a two weeks renewable visa for two more weeks and the conditions for it are as two-way ticket on the Qatari Airways, either the presence of immediate relatives in Qatar or booking at a hotel, and an amount of 5000 riyals or its equivalent in possession.

I recommend you to go with first option!
