Safari Land Resort is a great budget option resort with great facilities
The Hill Country Holiday Resort is located sufficiently close to the main town of Ooty and is a good budget option Located on a gently sloping hill overlooking the Ketti valley, this resort is a peaceful place wherein to spend your holidays.
Basically boils down to your budget (both for the stay and for travel). Cab would be your best bet for the travel, else a combination of train / bus would be possible (Train until Mysore from Bangalore and a Bus / cab from Mysore to Ooty & Back)
Safari Land Resort is not at Ooty - it is at Masinagudi.
