Basically want to know how much to expect to spend ( Lodging, park fees, food etc) AND What will possibly be open while we are there. We badly wanted to do Glacier point but from previous advice it sounds we may not be able to do that unless we came late may! Hopefully this is not the case and we can plan a hike from the valley floor.
Also, is it suggested you go in large groups? I'm from Canada and I am used to large wildlife ( Bears, moose, wolves, cougars ) but here they are just afraid of people and run away, are they a bit braver in Yosemite due to the high amount of visitors it gets every year?? Just want to know if we should pack some bear spray as its just the two of us and we plan on doing A LOT of hiking. May have a few more questions to follow but this is enough for now!
