Booking; schedules fill up very fast so booking is often more difficult to secure. I find that it is now necessary to book about almost a month in advance. While this is not always easy for me, it is definitely not as doable for others I know. The limitations as well on credit transfer is very frustrating. Through a pandemic many credits were accrued. I'd love to be able to share these credits with my fiance, but 1 every 6 months is a joke, very limiting and seems unfair. Especially when it was once advertised you could transfer within the household (but was not honored and a lawsuit ensued changing the rules.. for not much better advantage to the consumer).
