For places, bustling is positive and lively, crowded and packed are neutral to negative, and teeming is vivid and slightly literary. Hopping is casual praise for a lively bar or club.
For time, hectic means fast and a bit chaotic, frantic adds panic, and eventful means a lot happened, often in a good way. A calm but full week is simply full or packed.
Busying yourself, and busy people by nature
As a verb, busy usually appears as busy yourself with: she busied herself with the dishes. Swaps include occupy yourself, keep yourself occupied and get on with.
When busy describes a person's habits, positive words fit: industrious, tireless, energetic and productive. Busy is not the same as productive, though. Plenty of people stay busy from dawn to dusk with little to show for it.
Mix-ups to avoid
Engaged means busy only in set phrases (the line is engaged, otherwise engaged). On its own, she is engaged usually means she plans to marry. Occupied on a restroom door means someone is inside, not that they are working. Overwhelmed describes a feeling of not coping, which is stronger and more personal than having a lot to do.
Opposites of busy
Free and available are the neutral opposites for people. Idle can sound lazy, so use it for machines or quiet periods. Quiet and calm suit places and days, and leisurely describes a slow, relaxed pace.
