I have multiple stays at Pop and CBR, I am just back from CBR last month. The construction IS an eyesore, but certainly not a deal breaker. The new Spyglass CS is great! You don't like one bus stop at Pop (???) but how do you feel about the delays it takes to make multiple stops within a resort?
CBR is MUCH more quiet than Pop and the rooms are larger. I love having multiple, quiet pools.
