In 37 short days we will be doing back to back Tauck tours. The first is Spain & Portugal and then we do Northern Spain. We recently got the detailed itinerary and under Clothing & Packing Suggestions it states that Sport coats for men are required for the palace dinner. I know some men do bring these on tours, but my husband just brings a dress shirt and slacks and that has been fine for the 3 trips we have been on to date. Since we will be traveling a total of 30 days, we would prefer not to bring a sport coat. Does anyone have experience with this tour and the requirement? Will we be unable to go to the "palace dinner" (I'm not even sure what palace dinner they are referring to on the itinerary). If not, we will make other arrangements. Thanks!
