Yes they will hold for you ......however, keep in mind if you are staying at one of the convention hotels (BW or BWV, YC/BC, BCV, GF, CSR, Contemp or BLT, they will charge you a fee for accepting a package. I believe they only do this at the convention hotels ......not sure if they've started charging at all hotels. I paid $5.00 fee at BCV in May when Bell Services delivered our package to us. If you are staying at a convention resort, the package will be delivered to their "package room". If you do choose to send a package, make sure in addition to the name/address of resort you have please hold for name/guest check-in date on the box. Others have also put their room confirmation #. I have not done that.... only my checkin date. Also, both UPS and FedEx have a time/cost calculator on their websites so you can determine when to send your package for it to arrive on your checkin date, or at least at close as possible (i.e. your check-in is on a Sunday, you probably want your package to arrive on Friday....I think most businesses do have Saturday delivery, but, to be sure I would shoot for Friday) Really no need to overnight......too cost prohibitive to make it worthwhile.
I've been sending a package ahead for at least 4 years.......probably 7 or 8 visits and have only had a small problem once....at BWV.... we were checking in on New Years Day......so because of the holiday week.....I needed to send my package a little early.....I think it arrived on the 29th. When we checked in there was no record of a package having been received at the front desk, but, I had my confirmation from FedEx that it had been received and signed for. It took a few hours but it was found in the package room at the convention center at BW.
