Cruise-neophyte

We are looking for ships that may have a larger shower, if it exists, as one of us is a larger person.  We would we be in a balcony stateroom with Royal Caribbean Voyager of the Seas or Odyssey of the Seas.  Or Celebrity Infinity would likely work as well.  We look to travel to the Greek Isles so may consider other cruise lines but we are familiar with Royal Caribbean and Celebrity and have traveled them before.  We would not break the bank if it had to be some kind of suite.  Any ideas are appreciated.

Going to be on the Brilliance in a little over a week and looking at an excursion from RCCL to Stingray city reef, 7 mile beach and lunch.. I wonder how much time will we have with the stingrays and at the beach? Also, will we need to rent an umbrella and chairs or any provided with the excursion?

I have signed up for MyTime dining. If my DH and I are eating in the main dining room, will they seat us at a table with other people as well or just a table for 2?

If my DH and I participate in my time dining in the MDR, will we be seated by ourselves or with others?

On the Brilliance out of Tampa in February 2017, looking at flights home. Anyone do self-assist and what time were you allowed to leave?

How much would you tip the porter for 2 of us, each with a suitcase? Thinking about before noon (9:45, 10:25, or 11:15)flight and want to be sure to make it.

Thanks. More concerned about when they open in the morning as I can be an early riser.

Heading on Jewel of the Seas in a week! I wanted to know if the fitness center is only open certain hours or if there is 24 hour access to equipment?

Thanks

I'm glad I searched about the overnight parking. We do not need our rental car in Kauai until the afternoon. Is it possible with this permit to come and go as you please for the one fee? I thought I could get the car in the morning and then get the permit, leave the car until the afternoon, use it, and then leave it there overnight. Would I need to pay 2 fees?
