I would try to arrive before official opening time. We really like to rent a locker, put everything in it and be completely ready to slide at rope drop so we don't have to go find a chair, get situated and then get in line. If you are interested in Teamboat Springs, the family raft ride, I would get in line for the ski lift first. If not, I would head for the Snow Stormers/Toboggan Racers/Downhill Double Dippers area - those lines build pretty fast, particularly Downhill Double Dippers (I would probably do that first of the three). I would then go to the Runoff Rapids slides - these are our favorites, but the lines don't seem to get very long there (I think Double Dippers backs up because you have to wait for the rafts). I would then do the lazy river, wave pool, ski patrol or tike's peak areas - there never seem to be lines in those areas.
