Two questions about excursion in Georgetown please..

[luckyprincess]

:) Hi,

Can't wait to go here! But....there are 7 ships in port/tender for the day we will be there. We arent' doing any excursions through the ship or independently, but we were thinking of just renting a bike somewhere and cruising around the island. We would like to see the towns, I guess, the Hell post office for sure, no real shopping. Do you think there is somewhere to do that that isn't an excursion type tour thing? Also, do you think it would be a problem with so many people around? Just don't know much about the place and want to have a relaxing (but active ) day.
