This thread seems to address the concerns I have when planning my trip next month. Because I'll arrive in SIN near midnight at T1 and depart next morning 8am from T2 on a different airline (NH), the transit hotel (C/I: midnight, C/O: 6am) seems to be a very good option compared to Crown Plaza (SGD200+) in T3. If NH allows me to check-in for the flight next morning, that'll be ideal as I can pick up my checked bags from the first leg, give them to NH, and go to the gate area with my new boarding pass - no hurry in the morning. However, I don't know if it's feasible. Therefore, I'd have to trust that my bags can be found and retrieved in T1 next morning after I check out the transit hotel.

A few questions:
1. If the transit hotel in T2 is better than T1 due to the construction, how much time will it take to travel between T1 and T2?
2. How much time does it take usually to retrieve the unclaimed bags? This will help me plan the check out time at the transit hotel.

Thanks a lot.
