I want to make my reservation for a snorkel trip in GC but want to make sure we pick a time that works with the time change/difference. I'm totally confused with all of it We're on the Nov. 3rd cruise out of Galveston. We'll have the "fall back" time change during our 1st night (or at least I assume we will). Itinery says we're in GC at 7:30am. Is that Eastern time or Central time? Will we make the 9:15am (eastern daylight saving time) tour okay or should we go with the 11:15am? I don't want to worry about missing it with the tender thing but I would also like to have some free time in the afternoon for shopping. Thanks for your help!
