I'm doing one now. Everyday I'm questioning myself if this is a right decision. I took too many subjects (4 subjects) in my current semester. 4 night classes a week (3 hours each). plenty of assignments and mid sem exams. plenty of group discussions. basically losing my own personal time including weekends.

so my advice would be that find an mba which suits your workload and lifestyle. if you're working and work ends at 6pm normally, then it's okay to take more subjects, else do slowly, 2 subjects at a time. can also find mba which emphasized on more assignments or exams, depending on your preference. of course besides that price of mba, recognition etc will make a difference too.

just my 2 cents.
