7.3.1 Although travellers generally stay in commercial accommodation, the PSAC will authorize a traveller to make arrangements for private, non-commercial accommodation.  A traveller who makes such arrangements shall be reimbursed an amount in accordance with the PSAC Travel Policy (see Appendix A), for each night this accommodation is occupied in Canada or abroad (US$ in the United States).   The total cost of the private, non-commercial accommodation rate plus appropriate and economical local ground transportation should not exceed the commercial accommodation costs that would otherwise have been authorized.
