I do it fairly often since I increased my climbing to 4 times a week. Its when you don't ache after your sessions you need to worry... you're not trying hard enough!!
If you are aching, it means your muscles need time to recover. They need to recover to get stronger. Rest days are an important part of the process. Sometimes it's better to have short sessions and be fresh to climb again the next day. Depends what you want to achieve.
