As long as you're making sure your horse is taken care of I don't feel like there's any reason to feel bad about not being able to go see them a certain number of days a week when you're doing a full board and care, everyone has their own situation.
Currently I usually see my mare once or twice a week; I would like to go more often and I also sometimes get a feeling of "not doing enough", but in reality I am not reasonably at the point yet hat I can ride her without supervision. The family I board with encourages me to come out any time, I pay them for board and some extra for her training (they very graciously included any riding lessons I need into her board fee.) But, they are still working on getting their business up and running and property upkeep, the wife works outside the home and has to travel quite a bit, and they've recently had some damage to the property and problems with some neighbors that I know make it difficult for them to just drop everything when I come out for a lesson.
As I work toward being able to feel comfortable alone in the round pen or on a trail, I plan to spend more time with her. I'm still at the point of taking weekly to bi-weekly lessons and improving my knowledge and skill level. I just don't want them to feel like they have to stop and tend to me every time I show up. They've been extremely helpful and I just don't want it to feel like I'm taking advantage of them either. Also, because they've been working on a tune-up with her training that was desperately needed, I didn't necessarily want to be handling her all the time, possibly enforcing any bad habits they might be working to correct with my lack of experience. Once I'm able to ride solo I definitely plan on spending more time at the barn. I long for the day that I can leave work and just go ride. Right now between my schedule and theirs it just isn't ideal for me to be there more than I already am.
