Quick booking tips

• If you need privacy, request a 2‑ or 3‑bedroom apartment or ask for connecting/adjoining rooms (common family solution). Several of the listed hotels advertise “dual‑key,” interconnecting or two‑bedroom suites — always confirm bedding/configuration when you book. (quaywestsuitesmelbourne.com.au)
• For longer/family stays choose serviced apartments (full kitchen + laundry) — Adina, Oaks, Quay West, Peppers and similar brands emphasize kitchens/laundry. (adinahotels.com)
• Book direct with the hotel (or call reservations) if you need cots, rollaway beds, specific bed layouts or adjoining rooms — hotels can often confirm exact suite sizes and bed setups. (Policies vary by property.)
