I have gone to WW West 3 times and here are some things I can tell you. Warning this could be long.
You are put in cabins with about 12 other girls that are your age + a consouler. The cabins are really nice,they have AC and heater on both sides of the cabin,good bathroom and sinks(2 showers and toilets in each cabin and 4 sinks) and the beds are pretty decent not the super horrible camp beds. Your consouler is normally really nice,normally around the age of 18,19,20 so they are pretty cool,not like super duper strict or anything. Curfew is 10:00 lights out at 11:00 hill duty comes around every night between then and makes sure your in your cabin and brings night meds(to those who need have them). The girls in your cabin are really nice and your consouler will make sure of that
I have met people who have gone by themselves and who have gone with some teammates. Either way you will meet new friends and will have a great time. If you are on the shy side I might go with a teammate but you will still make friends,all the campers are generally nice and will make sure you have someone to hang out with. I know everytime I have gone I have made friends even though I went with my team and still keep in touch with the girls I met.
Also the staff is super nice. They are there to make sure you have a great time and feel comfortable. They will do anything to make sure you are happy. If it means changing cabins they will let you(once i switched cabins 3 times in 1 week and they didnt ask any questions they just wanted to make sure i was happy). The coaches are really nice and out-going. they will pull the best personality out of you, and all the other staff is super nice.
ON sunday night when you get there they will have skills testing to place you in a training group for the week. Basically they ask you what vault you can do/are working on, and you show them your best tumbling on floor and your best skills on bars. They rate you 1,2,3. 3 being you can do into the pit and 1 by yourself on floor. there are normally about 5 training groups. group 5- being rec,group 4- level 4s training 5,group 3- 5 training 6,group 2- being 6 training 7 and some level 7s and group-1 7s training 8 and above. So if you are going to be training level 8 you will be in group 1 or 2 depending on the skill level of that week. And most likely some of the girls from your cabin will be in your training group.
Some random facts are this. On sunday they take you on a tour of the camp,tell you the rules ect. The food is pretty good. Lots of choices. Breakfast there is always toast,bagles,a fruit bar, and cereal. Then there is the main course so waffles,pancakes something along those lines. Lunch you can still make toast and there is a salad bar. At WW West you can get a hamburger,veggie burger, or hot dog at lunch or dinner everyday if you dont like the main course. Dinner is the same as lunch. The rec activities are a ton of fun and the pool is awesome.
I hope this answers some of your questions. Feel free to ask any more Im willing to help.
