I plan to visit an art exhibition in Palazzo Strozzi in Florence, and I have the option of purchasing my tickets online ahead of time with a surcharge.
Clearly this makes sense only if the queue for online reservations is significantly shorter than the regular queue; otherwise it is just a waste of time, money, and flexibility. I have seen museums where pre-sale was a great time-saver, and museums where it was useless. What is typically the case with Palazzo Strozzi, in your experience?
If it matters, I plan to go there on a Saturday outside holiday season.
