That'll depend on the resort and the package. 90% of the time, you're right. If you have
your own equipment all you pay is the lift ticket. I have been to a resort in North Carolina
that makes you pay an insurance fee thats refundable, but I don't think thats very common,
seeing as how I've never seen it anywhere else. Thats why I cant say 100% certain though.

There are things you can add, like lessons, lift extensions for the resorts that offer night
riding, odd equipment rental, retune/detune, etc for the ever changing conditions which
usually arnt much ($10 at paoli and they set it from snow to ice in 20 mins).

Do a check before you leave...board, boots, bindings, leash, etc and make sure you have
everything and yeah, lift ticket is pretty much it! But it never hurts to bring extra money
just in case.

Check your resort, or if you're really feeling adventurous, a resort thats just alittle to far
for a day trip and see what kind of packages they offer. The one here, Perfect North
is at the very end of an "its ok to make in 1 day" trip, but if you stay at a hotel that participates
with the resort, you get free lift tickets. And sometimes this is actually cheaper than getting
the tickets from the resort (because they'll throw in a gift card or free rental or whatnot).
Perfect North and Holiday Inn offer a stay and ride package for $80 that includes shuttle
service, equipment rental for 2, and 2 lift tickets, plus a $10 gift card for the resort. 1 lift
ticket from Perfect North is $50...
I know thats alittle off topic, but it can give you some ideas for adventures in the future.

Oh and just for the information about the insurance this particular resort made us pay,
it was 10% of the lift ticket cost, which was $40, so oooh $4. You can call ahead if you
think this will worry you, but thats the ONLY resort that I've ever paid that at.

If it is your first time, most resorts have "packages" for Ticket/Rental/Lesson and Ticket/Lesson.  Since you have all your own gear already, you would need the Ticket/Lesson package.  Yes, I highly recommend the lesson.  Most last a couple hours and can show you the ropes, get you more comfortable and confident, and save you hundreds of falls!

If you have extra money bring it.  There are sometimes unexpected expenses that arrise.  Also be aware that you should have eye protection no matter what the weather conditions.  Goggles are the most appropriate and offer the best protection.  Dress in layers and get a locker at the lodge to keep stuff in.

HAVE FUN!!

^- oh man, paoli's food tastes like feet and perfect north's food tastes like cold feet.
So bring your own food just in case! Like sandwiches and stuff. They'll stay nice, cold,
and fresh in the car while you ride, and they're not $5 for a pbj.

Maybe this will help. Aside from equipment, this is my packing list:
1. Sandwiches
2. Water Bottles, or a refillable lexan bottle that you can carry.
3.Beer (optional)
4.Energy bars - you'll burn up so much energy within the first 4 hours its ridiculous.

Best part, you dont even have to buy ice! just wrap things up good and snag some
snow to throw in the cooler. The sandwiches, snacks, and water bottle will save
you around $20 easily.

Also if you want to save even more money, there's probably some friend you know
that would love to ride to, so pick em up and make them chip in on gas!

There are lots of ways to  make snowboarding cheap, you just have to be smart
about it.

Anytime bro
