Consistent level: the hotels in a proposal must all be of the same level, consistent with the client's budget. If you propose a simple 4-star, you cannot then put a luxury 5-star at another stop.
Exception — saving to "splurge": when the agent asks for it, you can save in some locations to invest in others. Typical example: simpler hotels in Florence and Rome, then stepping up a level in Como or Amalfi.
Exception — the competitive price: if a 5-star has a very competitive price in a given location, it can be included in a 4-star proposal. The reverse also applies: in an all-5-star proposal you can put a 4-star in a city where 5-stars cost too much.
Boutique hotels: if the client asks for small boutique hotels, the hotels proposed must be consistent with that request.
Hotels you don't know: you can check them on Booking.com. Never choose a hotel with a score below 8.5.
Location: pay attention to the location. In cities such as Paris, London, Rome and Venice, placing the client far from the centre becomes a logistics problem.
At the time of booking
Rooms: check that they have been booked correctly — twin or double as requested — and that the group has all the rooms it needs.
Stuba and GoGlobal: if a hotel is booked through Stuba or GoGlobal and the booking exceeds €1,000 (whatever the category), or if it is a 5-star, ask the hotel directly whether we can book direct.
