Per Sonny's suggestion, I contacted the tour operator and was advised that our ship will arrive too early to go on the day-long tour...so, now I'm looking at just the Dolphin Swim, without the lunch and beach portion, as an option.
I'm a critter person and would *really* enjoy swimming with the dolphins, me thinks (but, then again, they may not care for me at all...oh the risks one must take). My understanding DH completely comprehends the "if momma ain't happy, ain't nobody happy" statement, so...whatever makes me happy then!
So, if we arrive in St. Martin, is it a big deal to catch a ride over to Anguilla, do the "dolphin thing" and return to St. Martin without the support of a tour company?
Although I'm moderately well-traveled (married in Jamaica, bare-boated in BVI's, self-toured Belize), with the little time we're in port I'm concerned about getting my bearings and finding what we need...all without getting shafted in the process.
