Yes you should indulge in a spa treatment. They charge about 20% more than a regular service would on land, but it's worth it. Just be weary of the hype. They try to sell you "special products" that are over priced. I just say no thank you. I have had a manicure, facial and 60 minute massages. Ohhhh how good it makes you feel.
The excursions should have transportation included with the price. You can go the web site of RCC and look at what might interest you. Look on this site for information at the message board under destinations. Ask lots of questions there. Sorry I don't know anything about Mexico.
Hope this was some help.
man, poor you! I remember when I hit the month mark. It was the SLOWEST month of my life, well, IS the slowest month of my life. Feel's like it's been a year! Well, at least it's only a month. Im going nuts! Ive already packed some, and keep running out of clothes. I need new clothes anyways. I almost dont want to go on a cruise anymore because its annoying how impatient I am! lol. Happy cruising!
