Hi Karen!
I'd a look at your other messages; just to get an idea of how long you were going for etc.! You are a lot more organised than I ever was!
You'll have a great time-don't over think it as I tended to do-it's just walking and occasional talking!
PACKING: I've always brought a casual-easy to wash/dry dress for evenings-also for when I reached Santiago. I brought a pair of sandals as well, that doubled as walking sandals and evening sandals if my shoes began to hurt. Definitely bring a sleeping bag-I've only walked during the summer and there were times when I would have preferred a sleeping bag to a sleeping bag liner. Your list seems pretty much perfect-I've only ever brought a 35 too. Maybe bring an extra pair of socks and liquid clothes wash-available in any outdoor shop-made washing so much easier as it suds up much easier in cold water. Then again, you could be adding extras forever and end up with a house on your back!
WALKING: I've yet to walk to Finesterre, so I cannot advise you there. I've walked from Ponferrada to Santiago via Samos-which is very doable in 10 days. I'm not sure how easy it is, to get to, from Santiago, as I took an overnight train from Barcelona (city hols with friends beforehand). Sarria to Santiago is also a very doable 5 days and to Finesterre another 3. There are so many ways to do the camino, but whatever you decide to do, I know you'll be happy with it.
Bring a light bag-which it looks like you're already doing. There is plenty of accommodation on the
camino frances. It is the one thing I worry about before I go, as people say the camino is overcrowded and gets busier every year. However, I love the freedom of not booking and walking until I've had enough for that day. It always turned out fine.
EXPENDITURE: Daily spending roughly averaged out at 30e a day-coffee, medication, accommodation, food ( mixture of supermarket, cafe, communal meals, occasional menu de peregrino)
SAFETY: I've never felt really unsafe on the camino. There was just one time where I felt uncomfortable with a male pilgrim, so I hopped on a bus for 5km-met another female pilgrim on the bus who'd met him and had a similar story to me about him. There are usually so many people walking -you are never really alone!
Sorry for the long rambling reply. I'm probably repeating what many others have said before, but I hope it helps!
