I've a work trip away for 3 nights with 5 colleagues. They're busy, hectic days. Usually everyone is happy to eat in hotel that we stay in, and I'm happy with this as I can leave them drinking and just go up to my room when suits. I would describe myself as an introvert who needs a lot of time alone to recharge, especially after hectic days and I've spent all day with these people, who are colleagues, not friends.
Now, however, this time someone has suggested going out to different restaurants every evening to far side of the city where we'll be staying, which will involve taxis etc. I just don't want to do this and want to chill. Is this rude, or can anyone understand my need for downtime?
