I went looking for information last month whether I could earn points for 3 rooms I personally booked online via my account: my room + two family members' rooms. You can, per the T&Cs, earn on 3 rooms provided you occupy one room and pay for all rooms. In my case, I occupied one room, did not present a credit card in my name for any of the rooms, and all points posted.
I don't know if your school travel agent booking channel/rates fit into any of the exceptions listed below. If I were you, I would attach my BW number to 3 rooms and spouse/family BW number to the other 3 rooms.
EARNING POINTS FOR STAYS
All stays are eligible to earn points (“Eligible Stays”) with the exception of the following (Non-Eligible Stays”):
Stays booked through online travel agencies (“OTAs”), such as priceline.com, expedia.com, travelocity.com, booking.com, kayak.com (i.e., channels other than Best Western branded booking channels);
Stays booked through tour operators; and
Stays booked at special discounted rates, such as employee rates, FIT/wholesale/net rates, motorcoach/bus rates, crew rates, BWR free night awards rates (FX rates), or discounted rates for stays longer than thirty (30) nights.
What constitutes a rate or booking channel that qualifies as an Eligible Stay versus a Non-eligible Stay may change and so you should always confirm when making a reservation whether you are reserving a rate that qualifies as an Eligible Stay, for which you can earn Points, or a Non-Eligible Stay, for which you will not earn Points. This is more important if you are booking through a channel other than a Best Western branded booking channel.
You earn ten (10) Points for each $1.00 U.S. Dollar (or fraction of a U.S. Dollar) paid for an Eligible Stay, including VAT in certain areas outside the United States, but excluding amounts paid for non-VAT tax and incidentals. You can earn Points for up to three (3) rooms per Eligible Stay provided that: (a) one (1) room is occupied by you; (b) you pay for all the rooms; (c) Points for that room have not been issued to another Member; and (d) you presented your Best Western RewardsŪ membership number at the time of booking or at check-in.
